libr 1.3.9

• Removed some test data to reduce size of package.

libr 1.3.8

• Moved ‘nanoparquet’ to suggested instead of imports.

libr 1.3.7

• Added ‘parquet’ file format tolibname() function.
• Added ‘subset’ parameter todatastep() function tofilter the data on input.
• Added DATA NULL capability todatastep() function.

libr 1.3.4

• Fixed issue wherelibname() was failing on emptydataset.

libr 1.3.3

• Fixed issue wherelib_write() was not detecting changesto datasets in libname.

libr 1.3.2

• Fixed bug onlibname() when there are file names withmultiple dots.

libr 1.3.1

• Fixed bug ondatastep() when running insource.all().

libr 1.3.0

• Fixed bug on sas7bdat where class on date columns was beingstripped.
• Fixed bug ondatastep() where expression that wasremoving input dataset attributes (like labels).

libr 1.2.9

• Fixed bug ondatastep() when there are spaces in thecolumn names and output() function is used.
• Some improvements todatastep() performance.
• Send message on writing “sas7bdat” that functionality is notavailable.
• Added where clause parameter tolibname().
• Added automatic variables “first.X” and “last.X” for each byvariable.

libr 1.2.8

• Fixed bug on datastep that sometimes was causing variables to losetheir attributes.
• Added “where” parameter to datastep.
• Fix bug on datastep that was causing a single variable dataframe tobe returned as a vector.
• Cleared rownames on datastep exit.
• Added “MaxChar” column to dictionary to hold the maximum number ofcharacters for a data value in the column. This is different from“width” which is the user-defined, proscribed width. MaxChar is theactual width with no padding.
• Added “rda” engine to libname.
• Allowed single value NSE on drop, keep, and by parameter ofdatastep(). For multiple values, use thev()function.
• Addedoutput() function to datastep.
• Improved datastep output column ordering. New variables were comingout in the opposite order they were added. Now they are better.
• Added “set” parameter to datastep.
• Added “merge”, “merge_by”, and “merge_in” parameter todatastep().
• Fixed bug ondatastep() rename.
• Added/fixed documentation.
• Updated logo.

libr 1.2.5

• BREAKING CHANGE: Removed the%eq% operator from thispackage, as it has been moved to thecommon package. Adependency oncommon has been added to thelibr package so that the%eq% operatorwill be loaded and available. However, it is still possible some changesmay be required to make the new location for the%eq%operator work properly.
• Apply “format” parameter ondatastep() to both inputand output dataset.

libr 1.2.3

• Added “Rdata” option tolibname() functionengines.
• Added “label” parameter todatastep() function.
• Added “format” parameter todatastep() function.
• Addedlib_export() function to export a library to adifferent directory and file format.
• Fixed bug ondictionary() that was causing a warningwhen there were no rows on the input data frame.

libr 1.2.2

• Added FAQ and Complete Examples
• Fixed bug ondictionary() when encountering datetimevariable with multiple POSIX classes.

libr 1.2.1

• Added covr and codecov
• Fixed bug ondictionary() function that wasn’t showingwidth attribute.
• Fixed bug ondatastep() when applying attributes to acalculated variable.
• Small documentation fixes.

libr 1.2.0

• Made package compatible to R version 3.6.
• Added GitHub actions to test previous versions of R.
• Increased performance of datastep() function generally. Benchmarksshow about 40% improvement on average.
• Addedstandard_eval parameter tolibname() andlib_copy() functions to allow user to pass library names asa variable.
• Addedquiet parameter onlibname() function tominimize console output if desired.
• Addedarrays parameter anddsarray() class tohandle data step arrays. This functionality allows iteration across alist of variables inside adatastep().
• Addedattributes parameter anddsattr() classto handle data step attributes. This functionality allows the user toadd attributes to datastep variables.
• Fixed bug indatastep() where it was stripping columnattributes on Base R data frames.

libr 1.1.3

• Fixed bug on datastep when data frame/tibble had a singlecolumn.

libr 1.1.1

• Integrated libr with logr. All library functions will automaticallyprovide logging entries if the autolog feature of the logr package isenabled.
• Added pkgdown site.
• Addedfilter parameters tolibname() andlib_load() functions. The filter parameter allows the userto specify which data from the library they want loaded intomemory.
• Changed default “na” parameter on csv export to empty string insteadof NA to accommodate import into SAS. SAS couldn’t deal with the NAstrings.
• Fixed bug in dbf engine when outputting tibbles.
• Fixed bug in %eq% operator when comparing objects with differentnumbers of classes.
• Greatly improved performance of datastep, especially on groupedtibbles.

libr 1.0.1

A package to create data libraries, data dictionaries, and theability to perform a data step. The major functions are:

• libname() function creates a data library
• dictionary() function creates a data dictionary
• datastep() function steps through data row-by-row
• %eq% allows comparison of any two R objects withouterror

The packages also contains a variety of functions to manipulate datalibraries: *lib_load(): Loads a library into the workspace*lib_unload(): Unloads a library from the workspace *lib_sync(): Synchronizes the workspace with the librarylist *lib_write(): Writes library data to the file system*lib_add(): Adds data to a library *lib_replace(): Replaces data in a library *lib_remove(): Removes data from a library *lib_copy(): Copies a data library *lib_delete(): Deletes a data library *lib_info(): Returns a data frame of information about thelibrary *lib_path(): Returns the path of a data library *lib_size(): Returns the size of the data library in bytes *specs(): Create a collection of import specifications *import_spec(): Define an import specification for afile
