<\body> is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories by J 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. A first experimental interface with has been written by . This allows you to use R interactively inside and to easily include tables and the high quality plots from R into your scientific papers. <\initial> <\collection> <\references> <\collection> > > > > > > > > > > > > > > > > > >
