R is a language and environment for statistical computing and graphics. It is aGNU projectwhich is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T,now Alcatel-Lucent) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.
