%description
     R is a language and environment for statistical computing and
     graphics. It is similar to the S language and environment which
     was developed at Bell Laboratories (formerly AT&T, now Lucent
     Technologies) 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.

     R provides a wide variety of statistical (linear and nonlinear
     modelling, classical statistical tests, time-series analysis,
     classification, clustering, ...) and graphical techniques, and is
     highly extensible. The S language is often the vehicle of choice
     for research in statistical methodology, and R provides an Open
     Source route to participation in that activity.
