The R package sfsmisc has finally made it into a revision control system, and the fad of the day being git & github, so be it!
sfsmisc has been on CRAN for a very long time, and containing R code that is up to 17.5 years old. (See on how I got this into github, including parts of the long history.)
It is a collection of “goodies” as we used to call these nice utility functions. Whereas the package has been written and maintained by Martin Maechler, really there are quite a few more members of the SfS (Seminar fuer Statistik at ETH Zurich) who have authored some of the functions or contributed to them.
