The sassy package is a meta-package that installs a set of functions that aim to make R easier for programmers whose primary experience is with SAS® software. These functions provide the ability to create data libraries, format catalogs, data dictionaries, a traceable log, and includes reporting capabilities reminiscent of those found in SAS®. These packages were written independently, and the authors have no association with, approval of, or endorsement by SAS® Institute.

Packages Included

The packages included in the sassy meta-package are as follows:

  • libr: Define a libname, view data dictionaries, and simulate a data step.

  • fmtr: Create a format catalog and apply formats to a data frame or vector.

  • logr: Generate a traceable log.

  • reporter: Write reports and output in text, RTF, and PDF.
