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.
One of R's
strengths is the ease with which well-designed
publication-quality plots can be produced, including mathematical
symbols and formulae where needed. Great care has been taken over the
defaults for the minor design choices in graphics, but the user
retains full control.

R is an integrated suite of software facilities for
manipulation, calculation and graphical display. It includes
- an effective data handling and storage facility,
- a suite of operators for calculations on arrays,
in particular matrices,
- a large, coherent, integrated collection of
intermediate tools for data
- graphical facilities for data analysis and
on-screen or on hardcopy, and
- a well-developed, simple and effective
programming language which
includes conditionals, loops, user-defined recursive functions and
input and output facilities.
platforms are supported?
The R ( R-PROJ )
code can be compiled on many systems,
including Windows, Linux, and MacOS X.
