An open source programming language and software environment for statistical computing and graphics.

R is available on a wide variety of UNIX platforms, Windows and MacOS, and can be downloaded from CRAN. It is an implementation of the S programming language combined with lexical scoping semantics inspired by Scheme. R was created by Ross Ihaka and Robert Gentleman and is now developed by the R Development Core Team. It is easily extended through a packaging system on CRAN.
