In libr: Libraries, Data Dictionaries, and a Data Step for R

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 to libname() function.
• Added 'subset' parameter to datastep() function to filter the data on input.
• Added DATA NULL capability to datastep() function.

libr 1.3.4

• Fixed issue where libname() was failing on empty dataset.

libr 1.3.3

• Fixed issue where lib_write() was not detecting changes to datasets in libname.

libr 1.3.2

• Fixed bug on libname() when there are file names with multiple dots.

libr 1.3.1

• Fixed bug on datastep() when running in source.all().

libr 1.3.0

• Fixed bug on sas7bdat where class on date columns was being stripped.
• Fixed bug on datastep() where expression that was removing input dataset attributes (like labels).

libr 1.2.9

• Fixed bug on datastep() when there are spaces in the column names and output() function is used.
• Some improvements to datastep() performance.
• Send message on writing "sas7bdat" that functionality is not available.
• Added where clause parameter to libname().
• Added automatic variables "first.X" and "last.X" for each by variable.

libr 1.2.8

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

libr 1.2.5

• BREAKING CHANGE: Removed the %eq% operator from this package, as it has been moved to the common package. A dependency on common has been added to the libr package so that the %eq% operator will be loaded and available. However, it is still possible some changes may be required to make the new location for the %eq% operator work properly.
• Apply "format" parameter on datastep() to both input and output dataset.

libr 1.2.3

• Added "Rdata" option to libname() function engines.
• Added "label" parameter to datastep() function.
• Added "format" parameter to datastep() function.
• Added lib_export() function to export a library to a different directory and file format.
• Fixed bug on dictionary() that was causing a warning when there were no rows on the input data frame.

libr 1.2.2

• Added FAQ and Complete Examples
• Fixed bug on dictionary() when encountering datetime variable with multiple POSIX classes.

libr 1.2.1

• Added covr and codecov
• Fixed bug on dictionary() function that wasn't showing width attribute.
• Fixed bug on datastep() when applying attributes to a calculated 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. Benchmarks show about 40% improvement on average.
• Added standard_eval parameter to libname() and lib_copy() functions to allow user to pass library names as a variable.
• Added quiet parameter on libname() function to minimize console output if desired.
• Added arrays parameter and dsarray() class to handle data step arrays. This functionality allows iteration across a list of variables inside a datastep().
• Added attributes parameter and dsattr() class to handle data step attributes. This functionality allows the user to add attributes to datastep variables.
• Fixed bug in datastep() where it was stripping column attributes on Base R data frames.

libr 1.1.3

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

libr 1.1.1

• Integrated libr with logr. All library functions will automatically provide logging entries if the autolog feature of the logr package is enabled.
• Added pkgdown site.
• Added filter parameters to libname() and lib_load() functions. The filter parameter allows the user to specify which data from the library they want loaded into memory.
• Changed default "na" parameter on csv export to empty string instead of NA to accommodate import into SAS. SAS couldn't deal with the NA strings.
• Fixed bug in dbf engine when outputting tibbles.
• Fixed bug in %eq% operator when comparing objects with different numbers of classes.
• Greatly improved performance of datastep, especially on grouped tibbles.

libr 1.0.1

A package to create data libraries, data dictionaries, and the ability 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 without error

The packages also contains a variety of functions to manipulate data libraries: lib_load(): Loads a library into the workspace lib_unload(): Unloads a library from the workspace lib_sync(): Synchronizes the workspace with the library list 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 the library 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 a file
