## Software Description

R is a language and environment for statistical computing and graphics.
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.
## General Linux

To run this software
[interactively](https://www.msi.umn.edu/remote-access) in a Linux
environment run the commands:

    module load R
    R

Several versions of R are available, but the versions may be different
on different platforms.To list all versions of R available on the

    module avail R

We recommend that you install R packages in your home directory. It can
be accomplished by typing the following in the R command prompt. You
need to replace packagename with the actual package.

	r <- getOption("repos");
	r["CRAN"] <-[http://cran.rstudio.com];
	options(repos=r);
	install.packages("packagename");

Some packages need external libraries such as [gcc](https://www.msi.umn.edu/sw/gcc), [gsl](https://www.msi.umn.edu/sw/gsl), [fftw](https://www.msi.umn.edu/sw/fftw) etc.
You can find the requirements in the package documentation.
These packages have to be loaded by using 'module load' command before using R.
