# R

## Description

{{{name}}} website

R is a free software environment for statistical computing and graphics.
Template:App Location

## Available versions

**Note: File a support ticket to request installation of additional libraries.**

- 2.14.1-mpi - R base package MPI-enabled via the Rmpi library.
- 2.14.2
- 2.15.0 (default)

## Running the application using modules

To use R with the environment modules system at HPC the following commands are available:

Get module information for r:

$module spider R

Load the default application module:

$module load R

The modulefile for this software adds the directory with executable files to the shell execution PATH and sets the following environment variables:

- HPC_R_DIR - directory where R is located.
- HPC_R_BIN - executable directory
- HPC_R_LIB - library directory
- HPC_R_INCLUDE - includes directory

To use the version of R built for parallel execution with MPI via the Rmpi library load the following modules:

module load intel/11.1 openmpi/1.4.3 R

## Installed Packages

**Note: ** Many of the packages in the R library shown below are installed as a part of Bioconductor meta-library. The list is generated from the default R version.

## FAQ

**Q:** When I submit the job with N=1 and M=1 it runs and R allocates the 10 slaves that I want. Is this the OK?

**A:** In short, no. This is bad since you are lying to the scheduler about the resources you intend to run. We have scripts that will kill your job if they catch it and we tend to suspend accounts of users who make a practice of it. :)

Example of using the parallel module to run MPI jobs under R 2.14.1+

{{#fileAnchor: rmpi_test.R}} Download raw source of the [{{#fileLink: rmpi_test.R}} rmpi_test.R] file.

```
# Load the R MPI package if it is not already loaded.
if (!is.loaded("mpi_initialize")) {
library("Rmpi")
}
# Spawn as many slaves as possible
mpi.spawn.Rslaves()
# In case R exits unexpectedly, have it automatically clean up
# resources taken up by Rmpi (slaves, memory, etc...)
.Last <- function(){
if (is.loaded("mpi_initialize")){
if (mpi.comm.size(1) > 0){
print("Please use mpi.close.Rslaves() to close slaves.")
mpi.close.Rslaves()
}
print("Please use mpi.quit() to quit R")
.Call("mpi_finalize")
}
}
# Tell all slaves to return a message identifying themselves
mpi.remote.exec(paste("I am",mpi.comm.rank(),"of",mpi.comm.size()))
# Tell all slaves to close down, and exit the program
mpi.close.Rslaves()
mpi.quit()
