Description

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 on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS.

Versions and Availability

A current list of the versions available on the bwUniCluster and bwForClusters can be obtained from the Cluster Information System: CIS Information on R

On the command line interface of any bwHPC cluster, a list of the available R versions using

$ module avail math/R

Usage

Loading the module

You can load the default version of software name with the command

$ module load math/R

The module will try to load modules it needs to function (e.g. compiler/intel). If loading the module fails, check if you have already loaded one of those modules, but not in the version needed for software name. If you wish to load a specific (older) version, you can do so using e.g.

$ module load math/R/3.1.2

to load the version 3.1.2.

Program Binaries

Executing R in batch mode:

R CMD BATCH --no-save --no-restore <INPUT_FILE>.R

For help run

R --help

For command help run

R CMD command --help

Examples

The software module contains R examples for the bwUniCluster:

$ module show math/R
$ module load math/R
$ ls $R_EXA_DIR
$ cat $R_EXA_DIR/README
$ mkdir Rtest
$ cp $R_EXA_DIR/bwhpc-r.moab $R_EXA_DIR/fit.R Rtest/
$ cd Rtest/
$ nano bwhpc-r.moab                                # change job options
$ msub bwhpc-r.moab                               # submit job
$ checkjob -v <JOBID>                              # check state of job
$ ls                                                                # when job finishes the results will be visible in this directory

Version-Specific Information

For information specific to a single version, see the information available via the module system with the command
