sfsmisc

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.

DESCRIPTION

Useful utilities 'goodies' from Seminar fuer Statistik ETH Zurich, quite a few related to graphics; many ported from S-plus times.
