Instalate el paquete "R", el paquete "r-base". ¿Qué es R?:

R 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 (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. 

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 available as Free Software under the terms of the Free Software
Foundation's GNU General Public License in source code form. It
compiles and runs out of the box on a wide variety of UNIX platforms and
similar systems (including FreeBSD and Linux). It also compiles
and runs on Windows 9x/NT/2000 and MacOS.
