If truncating/dropping columns in the csv file, NMwriteData()
accepts data with commas in values, even when writing to csv
files. The way NMwriteData() writes csv files, commas in character
columns are a problem. But the trunc.csv.as.nm=TRUE argument means
that columns not used by Nonmem (i.e. including most character
columns) are not written to csv. Instead of rejecting these data
sets right away, NMwriteData() will now only return an error
ifcharacter variables with commas in values are attempted written to
csv file.
NMscanTables() includes model name in meta data table. Useful for
generation of overviews of output tables from multiple models.
NMscanMultiple would sometimes print a bit of a messy overview of the results. That has been fixed without implications on the results returned.
dt2mat() now returns actual matrix objects. This provides compatibility with the simpar package.
NMreadPartab() has been generalized to support comment formats very
generally. NMreadPartab() reads the comments in $THETA, $OMEGA
and $SIGMA sections, splits them into variables, and organizes
those variables in a parameter table. With this upgrade, pretty much
any structure should be supported as long as delimitors are not
alphabetic or numeric (so any special characters should
work). Notice, delimitors can change between fields . Example:
"$THETA 1.4 ; 3 - CL (Clearance) [L/h]" would be matched by
NMreadPartab(...,format="%init ;%idx-%symbol(%label)[%unit]")
which would then return a table including columns init, idx, symbol,
label, and unit. The comments must be systematic within say $THETA
but the format can be different for $OMEGA and $SIGMA. See
examples in ?NMreadParTab.
NMrelate() is a new automated approach to label parameters. It
interprets Nonmem code and provides labels used in the control
stream. If the line TVCL=THETA(1) is the only line in the code
that references THETA(1), NMrelate() will return a label
TVCL.
Improved support for character-coded TIME and DATE
arguments. The default behavior is to allow (not require) TIME and
DATE columns to be non-numeric. This is to support the Nonmem
character format of DATE and TIME. It affects sorting of columns
(NMorderColumn()) and the auto-generated $INPUT section
suggestions. Where applicable, the allow.char.TIME argument
controls this behavior. Set to allow.char.TIME=FALSE to require
TIME and DATE columns be numeric. Thanks to Sanaya Shroff for
the request, enabling NMsim to simulate using data sets with one
or more of these columns coded as character.
mergeCheck(x,y) has new options for handling common columns in
data sets. The common.cols argument replaces fun.commoncols with
added functionality.
common.cols="merge.by" to include them in by, even
if they are not provided in the by argument.
common.cols="drop.x" to drop the columns on the x and
overwrite with columns in y
common.cols="drop.y" to preserve in x
base::stop The default value. Throw an error if common.columns
are not included in merge by options.
common.cols=NULL disabled handling and return columns as ".x"
and ".y".
Any function. common.cols=warning will issue a warning instead
of throwing an error.
NMreadExt() separates objective function values into a separate list
element. The return argument is used to control what data to
retrieve. Use one of "pars" (default, parameter estimates),
"iterations" (parameter estimates for each iteration), "obj" for
objective funtion value, or "all" for a list with all of those.
NMreadExt() adds block information to OMEGA and SIGMA elements
based on off-diagonal values. iblock identifies which block the
element is in. blocksize is the size of the block the element is
in. Thank you Brian Reilly for contributing to this.
NMreadExt() adds a par.name column which is provides consistent
parameter naming. Instead of Nonmem's THETA1 which is found in the
parameter column, the par.name column will contain THETA(1)
consistent with the OMEGA and SIGMA naming like OMEGA(1,1)
NMreadExt() recognizes Laplacian estimation steps in addition to
the already supported FO, FOCE(i), SAEM, and IMP.
A new option nc can be controlled with NMdataConf(). This is to
serve NMsim. Please see NMsim::NMexec. NMsim::NMsim() does not
adhere to this setting because it does not parallellize by default.
NMscanInput() and NMreadCsv() could fail if file names had no
extensions. Fixed.
NMreplaceDataFile() now works on directories and regular
expressions to find models to update.
Some internal functions would make some functions including
NMscanData() fail if used within lapply(). Fixed.
NMexpandDoses() would give a warning if length(cols.id)>1. Fixed.
NMreadExt() would mess up iterations and parameter estimates if
as.fun was set to returning something else than data.tables. Fixed.
Function NMreadShk() to read and format .shk (shrinkage) files.
Functions mat2dt() and dt2mat() included to convert between
matrices and data.frame format of matrix data - especially for
symmetric matrices.
Function addOmegaCorr() adds estimated correlation between ETAs to
parameter tables, as obtained using NMreadExt().
fnAppend() can now handle multiple strings to append. Allows for
more easily readable code.
NMcheckData now respects NMdataConf() setting of col.time and
col.id. When using the file argument col.id was not respected
at all. Fixed.
addTAPD would get cumulative counting of number of doses and
cumulative dose amount wrong in case of repeated dosing (using
ADDL and II) followed by other doses. Fixed. Thanks to Simone
Cassani for catching it.
countFlags no longer needs a table of flags. By default it will
summarize the ones found in data. If additional flags wanted in
summary table (with no findings), the flag table is still needed.
If a flag table is provided, countFlags will throw an error if the
flags found in data are not covered by the provided flag table.
NMorderColumns now includes arguments col.id and
col.time. These can now also be controlled using NMdataConf().
NMreadParText includes argument modelname, col.model, and
as.fun and defaults to what is defined in NMdataConf() like
other NMdata functions. It also includes a parameter column for
easier merge with data from e.g. ext files NMreadExt().
NMreadParText accepts function (with the control stream path as
argument) to define how to read the parameter information. This is
useful if one defines the tabulated information in a comment in the
control stream. NMreadParText basically allows for a full automation
of flexible parameter table generation.
NMdataConf() is configured to handle NMsim's dir.sims and
dir.res.
NMdataConf(reset=TRUE) wipes all settings. In recent versions,
NMdataConf accepts the allow.unknown argument which means
settings that are unknown to NMdata can be stored. This is
relevant for other packages that want to make use of NMdata's
configuration system (NMsim is an example of a package that does
so). Now NMdataConf(reset=TRUE) makes sure to wipe all such
configuration if exists.
NMreadParsText() is a new function to extract comments to
$THETA, $OMEGA and $SIGMA sections. As long as the comments
are structured in a table-like manner, NMreadParsText() should be
able to fetch them almost no matter what delimiters you used. Use
say fields="%init;num)symbol/transform/label(unit)" if you have
lines like
(0,1) ; 1) CL / log / This is clearance (L/h)
All comment lines don't have to be completed, and you can specify
separate formats for $THETA, $OMEGA and $SIGMA. Together with
NMreadExt() this is a very flexible basis for generating parameter
tables.
colLabels() is a simple wrapper of compareCols() that extracts
the SAS column labels on data sets.
NMdata functions will now by default look for input control streams
with file name extensions either .mod or .ctl. The user
previously had to tell NMdata to look for .ctl using configuration
options or function arguments but it will now work either way. An
error will be thrown if both should be found.
NMreadExt will by default only return parameters and iterations
from the last table available. This can be controlled by the
tableno argument.
fnAppend will now throw an error in case the file name extension
cannot be identified.
NMreadText would fail to disregard some comment lines when
keep.comments=FALSE. Fixed.Better support for models with multiple estimation steps. Particularly reading output tables now better distinguishes between Nonmem table numbers and repetitions (like SUBPROBLEMS). Also, functions that read parameter estimates clearly separates Nonmem table numbers.
Improved support for reading multiple models with NMreadExt and NMreadPhi.
translate and
recover.cols.format
arguments.type.data which allows switching
between estimation and simulation type data.dir) only.The super fast fst format is now supported. Data sets can be
written to this format, and NMscanData() and related functions can
read it. It can be used instead of rds which is the default
full-featured data format used in the package.
New function NMreplaceDataFile to replace the input data file in a control stream. A simple wrapper of NMwriteSection but useful for this specific purpose.
New function editCharCols that allows for editing character columns in a dataset based on regular expressions or strings. This allows for instance for removal of special characters that are not allowed in the selected data format (like a comma can make trouble in a csv file).
NMcheckData has a new argument, cols.dup, to include additional
columns (to col.id, col.cmt, col.evid, and col.time) in search for
duplicated events. This is useful for different assays run on the
same compartment (say a DVID column) or maybe stacked datasets. If
col.cmt is of length>1, this search is repeated for each cmt
column. Thanks to Eric Anderson for suggesting and testing this.
NMcheckData has improved checks of II and ADDL columns.
NMwriteData now uses the formats argument to specify the requested
file formats. This replaces arguments like write.csv and
write.rds. To get those two, do formats=c("csv","rds") (which is
default). The argument save is used to control whether outputs are
written altogether.
Argument name format has been cleaned and aligned to follow the an.arg format rather than camel toe which was also used in some functions before. All deprecated arguments have been soft deprecated meaning they still work.
This release provides a few bugfixes, nothing major.
skip.absent argument.Filtering by the abbreviated IGN notation in Nonmem control statements would not always work when not using a row identifier for combining input and output data. This should now be fixed. However, it is still recommended to use a row identifier to merge input and output data.
flagsCount now reports NA discards for total and analysis data. It used to report zero but these criteria are not applied at these steps.
NMcheckData has improved checks of some columns related to either observations (like MDV) or doses (like RATE). This will give less findings that Nonmem would not fail on anyway.
addTAPD's col.ndoses argument has been renamed to col.doscumn and the default value is now "DOSCUMN". This makes it clear that it is a cumulative number and it aligns with col.doscuma which is the cumulative amount.
NMwriteSection() includes argument location. In combination with
section, this determines where the new section is
inserter. Possible values are "replace" (default), "before", "after",
"first", "last".
NMreadSection() adds support for partial matching of section
names. Specifically, this means that the first three characters will
be matched only, i.e. allowing say $SIMULATION to match $SIM or
$ESTIMATION to match $EST.
NMcheckData() did not check columns listed in cols.num for NA
elements. Now it does.
NMcheckData now only checks col.dv to be non-NA for col.mdv==0 if
col.mdv is present.
NMscanInput() would fail if there was no column called ID in the dataset
on file. This has been fixed to support cases where renaming or a
pseudonym is being used to generate an ID column in $INPUT.
This update is of no difference to users. A technicality has been chaned to ensure consistent test results once data.table 1.14.7 is
fnExtension() has been generalized. It now ignores leading spaces in
new extension, and extensions with zero or one leading period are
treated identically (so asking for xml or .xml is the same). Also,
by providing "" as the new extension will now remove the extension,
and if extension is not provided, fnExtension will retrieve the
extension rather than replace it.
NMscanData() now supports repeated output tables, like those created
using the SUBPROBLEM option.
NMwriteData() has a new argument csv.trunc.as.nm. If TRUE, csv file
will be truncated horizontally (columns will be dropped) to match
the $INPUT text generated for Nonmem (genText must be TRUE for this
option to be allowed). This can be a great advantage when dealing
with large datasets that can create problems in
parallellization. Combined with write.rds=TRUE, the full data set
will still be written to an rds file, so this can be used when
combining output and input data when reading model results. This is
done by default by NMscanData(). This means writing a lean (narrow)
csv file for Nonmem while keeping columns of non-numeric class like
character and factor for post-processing.
NMwriteData() has got an arguement 'genText' to control whether text
for Nonmem should be generated. Default is to do so. Also, support
is added for script=NULL which now means the same as not specifying
script.
addTAPD() now includes SDOS, a scalar to be applied when computing
last dose amount and cumulative dose amount from AMT. Sometimes, AMT
is in one unit, and other variables related to doses is in
another. Say that dose is in mg and concentrations are in ng/mL,
then AMT should be in mcg. But you may want everything else
related to doses to be in mg. Then use SDOS=1000.
addTAPD() includes convenient prefix.cols and suffix.cols arguments
that will prepend or append strings to all created columns. This is
useful if dosing more than one drug, and you want to run addTAPD() for
both (different suffixes?), or if you want to run for nominal and
actual time (prefix A and N?).
flagsAssign() now reports that data is empty and return the data
if nothing is left after applying subset. It used to return an
error.
NMgenText() has a new argument, width, passed to strwrap to control
the width of the $INPUT text for Nonmem.
NMapplyFilters (and then NMscanInput and NMscanData) gave an error when multiple filters were applied on the same column. Fixed.
addTAPD() was not respecting subset.dos for all generated columns.
NMisNumeric() would interpret a NA of class character or logical as
non-numeric. Fixed.
Internally, combination of input and output data without a row identifier is simplified.
NMdata version added to welcome message.
NMexpandDoses() - Transform repeated dosing events (ADDL/II)
to individual dosing eventsaddTAPD() - Add cumulative number of doses, time of last dose,
previous dose amount, cumulative dose amount, and time since
previous dose to datatmpcol() provides column names not already used in data sets. tmpcol
has long been part of NMdata but has not been exported until now.xgxr package. Doses are implemented
using ADDL and II (so only one dosing row per subject). It is
included for testing the new NMexpandDoses and addTAPD functions.Vignettes are no longer included in R package and can only be read online at https://philipdelff.github.io/NMdata/ They are still being maintained, and the exclusion from the package releases is only due to CRAN's restrictive requirements to the package size.
New function, NMscanMultiple(), to read multiple models and stack
results in one data set. This is very useful for meta
analysis. NMscanMultiple() is a wrapper of NMscanData(). It keeps track
of warnings and errors for reading of individual models rather than
getting stuck. You can either specify a vector of model paths or a
directory plus a regular expression (just like for NMwriteSection).
Improved tests of order of age of output control streams and input data in NMscanData. So far, all data were tested on file modification times which is not useful in the common case that data files and/or nonmem control streams are moved around between systems. Now NMscanData can look for a time stamp in the output control stream and if NMwriteData was use to write the input data to file, the creation time is taken from meta data. This will make the warnings about the order of age of files more reliable. Notice however, that for the output control stream, the timezone has to be set using the tz.lst argument or using NMdataConf - at least for now.
Checks of unique subject identifier (usubjid) included in
NMcheckData. This is mostly to detect the potential issue that the
subject IDs generated for analysis are not unique across actual
subjects. If a usubjid (e.g. from clinical data sets) is included in
data, NMcheckData can check this for basic properties and check the
analysis subject ID and the usubjid against each other.
New function: cl - creates factors, ordered by the appearance of the elements when created. cl("b","a") results in a factor with levels "b" and "a". This can save quite some typing in data set preparation.
New function: fnAppend - append a string to a file name before the file name extension. fnAppend("data.csv","subset") results in "data_subset.csv".
General support for a file.data argument when a specific input data file is to be used instead of finding this information in the control streams. This is very useful if you archive input data together with a nonmem run in a way that the path in the control stream has to be overruled. Like many other of this type of arguments in NMdata, it can be a function that systematically converts the path to the control stream to the input data archive. Running Nonmem this way breaks the link between an input dataset that may change over time and the model runs that become self-contained packages of input and output data.
Support for NOHEADER option in Nonmem $TABLE blocks. If NMdata is
used to read the results, there is no need to use NOHEADER (which
opens the door to mistakes if manually renaming the columns in
results), but NMdata should now also be able to handle this.
If found in data, CMT is added to the breakdown of rows when
summarizing results from NMscanData. Before, it was broken down on
EVID only. Also, a total line is included with total number of rows
in each of input-only, output, and result.
Support for non-event (say for $PRED) datasets in NMcheckData.
Support for custom column names for DV (col.dv) and MDV (col.mdv),
ID (col.ID), AMT (col.amt) in NMcheckData.
Support for file.mod and dir.data arguments in NMcheckData when running on a control stream.
NMgenText now has an argument called until that specifies the last
column(s) to include in $INPUT.
compareCols takes the list.data argument same way as dims()
does. This is often easier to use in programming.
If NMgenText does not find any Nonmem-compatible columns to report,
it now throws a warning and returns NULL.
NMcheckData's ability to find data files when using the file
argument in NMcheckData. Only affects certain models.compareCols now by default lists the columns where no differences were found.
NMreadTab throws a message instead of a warning in case duplicate
column names are found and removed.
NMwriteData now runs NMgenText in try, just in case.
fnExtension now supports adding extensions to strings without
extensions, i.e. fnExtension("file",".txt").
NMcheckData is a new function that checks data for Nonmem compatibility in numerous ways. It returns a list of all findings making it easy to identify the location of each issue in the data. See the man page of NMcheckData for a complete list of the checks that are done. The function does not modify data in any way, and it is a very simple and easy step to avoid many problems in Nonmem. NMcheckData can check a data object in R, and it can also check how a control stream reads data and then do all the checks. The latter provides an extensive check of potential issues related to data and getting it into NONMEM. Great for both debugging and QC.
NMextractDataFile is a function that identifies the input datafile used by a Nonmem model. It reports the string as in the Nonmem control stream, file path and whether the file exists. It also looks for the corresponding rds files. The function is not new in NMdata but was not exported until 0.0.10.
cc is a function that creates character vectors from arguments without quotes. This is just to be able to skip typing quotes when listing say column names. So do cc(a,b,c) to get the exact same as c("a","b","c"). You cannot do this with strings that contain special characters. In that case do cc(a,"b+c") to get the same as c("a","b+c").
NMwriteSection has been updated with a few very useful features. Namely these are related to updating multiple nonmem files at once. The user can now supply multiple paths, regular expressions for finding files (like pattern in list.files) and even input data files for nonmem models to match. This is very useful when updating many models after modifying input data. You can specify say all models in a directory names like pd*.mod where * is anything (in regular expressions this would be "pd.+\.mod") and only the using the data file that was just written. Since NMwriteData generates the $INPUT for you, you just need to add one line to get the update of all your models automatically.
flagsAssign has got a few updates related to separate handling of different types of events. Often, this will be used to assign flags to observations, doses etc. separately. You can easily specify a subset of data to run flagsAssign on, and it will by default check for whether values of EVID are unique. This is similar to what flagsCount does.
NMgenText is a new function that provides the generation of $INPUT and $DATA. This used to be part of NMwriteData. NMwriteData still calls NMgenText but the separation of the two functionalities allows for more intuitive separate uses of one dataset for different models.
NMcompareCols now takes the argument "cols.wanted" which is a character vector of column names of special interest. Helpful when building a data set with specific column names in mind.
egdt now reports dimensions of the two data sets to combine and the resulting data. Can be disabled with quiet argument.
NMcheckColumns Change of column name from DATA to INPUT in order to match $INPUT in the control streams.
NMreadSection is now case insensitive in the section specification (i.e. "input" is the same as "INPUT").
In NMwriteData the datafile is now correctly included in the $DATA suggestion for Nonmem. No impact on data file output.
Bugfix in NMscanData related to searching for candidates for unique row identifiers.
In compareCols multiple classes of single columns would give a warning and sometimes confusing overview of columns. Fixed.
findCovs fixed in ordering output when by argument is of length > 1
The only change from 0.0.8 is a patch provided by Matt Dowle ensuring that tests pass after the release of data.table v1.14.2.
Meta data system rewritten. NMinfo and NMstamp are used to read and write meta data. Meta data is stored as an attribute to the data object (attributes(data)$NMdata).
Translation table includes a column ranking the match between input data file contents and $INPUT. OK: names match, diff: names do not match, off: diff and name is found elsewhere.
NMscanInput, NMaplyFilters, NMtransInp all return meta data compatibly with NMinfo.
merge.by.row="ifAvailable"
Check for new values of row identifier
Check for disjoint ID's when ID-level output tables found
Improved message from NMscanData
Support for custom (and NULL) values of col.model and col.nmout
Support for Nonmem filters without operators (COL XX)
NMreadCsv, NMscanInput, and NMscanData take argument args.fread. The contents of this list are passed as arguments to fread when reading csv files. This should only be needed in rare cases but offers full flexibility to match structure of csv files. Default contents of args.fread can be controlled using NMdataConf.
NMwriteData updated with more concise message.
NMreadSection now returns all sections if argument section is missing or equals NULL or ".".
NMinfo is a new function that provides meta data, processed by as.fun.
If merge.by.row=TRUE, NMscanData now checks if col.row seems to be changed in the Nonmem code. If that is the case, an error is returned.
save argument added to flagsCount function to align with other functions.
NMwriteData now writes meta data to a txt file when writing csv file. NMreadCsv looks for this info and attaches it if found.
NMwriteData takes the argument args.fwrite - a list of arguments passed to fwrite. This is aligned with args.fread used by NMreadCsv. Defaults can be configured using NMdataConf.
Improved and shortened text to console from NMscanData (print.summary_NMdata).
mergeCheck will now throw an explained error if argument df1 has zero rows.
compareCols generalized to the single data set case.
mergeCheck has improved warnings when checks fail. This should in most cases provide information for the user to get a good idea what needs to be resolved for the merge to work as expected.
Support for pseudonyms when translating input data column names based on nonmem control stream. Now by default, the column will be returned (doubled) with both pseudonyms as column names.
new function - fnExtension is a simple function to replace the extension of a file name (say from file.mod to file.lst)
new function - dims is a simple function that returns a table of the dimensions of multiple data sets. It is used by multiple other functions in the package and may be useful on its own. However, compareCols reports this information too (by calling dims).
NMscanData now has an argument, translate.input, which can be used to skip the translation of column names according to $DATA in the listing file. This can be necessary if input data has changed and hence $DATA is outdated since last model run.
flagsCount now reports cumulative counts of discards too.
This is a major upgrade from 0.0.6.6 featuring many improvements and bug fixes. Everyone is strongly encouraged to upgrade.
The choice between data combination methods in NMscanData is now done in one argument, called merge.by.row. Before the method was decided based on values of two arguments, cbind.by.filters and col.row. A default value for col.row can now be set using NMdataConf and will not affect the data combination method.
Other arguments which default values can now be modified using NMdataConf are: merge.by.row, col.flagn, col.flagc, use.input, recover.rows, col.model, modelname, file.mod, and check.time, quiet, use.rds.
The tools to assign and count exclusion flags, flagsAssign and flagsCount, have been improved. They now support working on a subset of data (say samples only), and the order (increasing/decreasing) of the exclusion flags is optional. The printing of the count of exclusion flags has been improved.
NMgetSection and NMwriteSection are new functions that can be used to extract sections from and write sections to Nonmem control streams. NMwriteData now returns a list of sections that can be passed directly to NMwriteSection, in order to update control streams to read the updated data file correctly.
compareCols is a very useful new data creation tool. See the difference between presence and classes of columns in data sets. This is useful before rbind'ing or merging - or maybe when those throw an error, and you want to figure out why.
renameByContents is a function that can rename columns which contents match a given criterion. In combination with the provided NMisNumeric, this can be used to rename (say to lowercase) columns that Nonmem cannot interpret (as numeric).
mergeCheck now informs about common column names that are not used to merge by. These will create new column names, and it's often not intended. An argument has been added (ncols.expected) to check the number of columns added to df1 against expectation.
egdt is a new function for expanding grids of data.tables. This is quite technical, and it fills a whole when constructing data with data.tables. It mimics the behavior of merge.data.frame on objects with no common columns.
Central configuration mechanism implemented. The configuration function to use is NMdataConf. You can configure several options, corresponding to default values of arguments to different functions in the package. This is very useful if you want to change the directory and file naming structure, or if you want to change default column names.
The exclusion flag functions flagsAssign and flagsCount have been generalized to use customizable column names for the numerical and character flags. The default can be configured using NMdataConf.
If all common column names two data objects to merge are not used for merging (by), new column names are created by merge. The behavior of mergeCheck can now be controlled in case this happens. This is especially useful when using mergeCheck in programming.
A shortcut to system.file(...,package="NMdata") has been removed. The function was called NMdata_filepath and is no longer available. Use system.file instead.
Meta information added about the input data.
A summary function is provided for NMdata objects. There is a print function for the summary too. This is printed automatically by NMdata unless quiet=TRUE.
A lot of meta information has been added in an attribute to NMdata objects. This will help the user to understand and automatically document what has been read.
The argument to NMscanData previously called name has been renamed to modelname and generalized to take a function that derives the name from the file path. Also an general option "NMdata.modelname" has been added, so the default behavior can be configured.
The default class to generate is now data.frame rather than data.table. If you want to work with data.tables, do options(NMdata.as.fun="none")
General support for conversion of output to user-specified class. Setting the option "NMdata.as.fun" to a conversion function such as as.data.frame or tibble::as_tibble it is possible for the user to work with their preferred data class. An argument, as.fun, can be used for the individual functions too.
The translation from the output control stream file path (.lst in PSN) and the input control stream (.mod in PSN) can now be configured through the option "NM.file.mod". Typically, all the models to be considered in an analysis have been run on the same system, so it makes most sense to define this behavior once and for all for most users.
NMwriteData improved with checks of column names and automated generation of $INPUT and $DATA Nonmem sections.
NMorderColumns simplified, and documentation improved.
Documentation has been upgraded with a pkgdown site.
New vignette on data set creation tools in NMdata.
New FAQ vignette.
NMtransInput now supports the case where additional unused column names are given in $INPUT than actually found in $DATA. A warning will be given.
This release introduces a consistent default NMscanData behavior that will work in most cases and provide the user with information on how to use a more robust approach to merging input and output data.
Naming of a few arguments to NMscanData has been changed from camelCase to lower.case for consistency.
NMscanTables keeps track of LASTONLY and FIRSTLASTONLY. LASTONLY are now treated like FIRSTONLY while FIRSTLASTONLY tables are disregarded (with a warning).
The most obvious change since 0.0.3 is that only one data.table is
being returned from NMscanData. This is what used to be the row
element in the returned objects previously. The main reason for this
change is that it makes it easier for users to post-process only one
dataset before splitting into different levels of variability. The
small cost is that the user will have to run findCovs, or findVars to
get the desired level of variability. These functions are however very
simple to use and very fast to run.
This release features numerous improvements to especially the NMscanData function. The work is mainly focused around use without a row identifier. Even without a row identifier, NMscanData should now work for the vast majority of models, including merging with input and recovering rows.
An attribute called vars has been added to the NMdata objects coming
out of NMscanData. It features a table of the columns in the returned
object and information about where they originate from. More work is
still to be done on this, but hopefully it is useful already.
NMwriteData: Added support for passing arguments to saveRDS.
Last but far from least is a new vignette on using NMscanData. Check it out with vignette("NMscanData").
This release contains bugfixes and experimental support for merging nonmem input and output data without a row identifier.
A clearer cut has been made between the pmxtricks package (version 0.0.10) and NMdata. The packages should not overlap in exported functionality, and they do not depend on each other.
