R is an integrated technical computing environment that combines sophisticated computation, advanced graphics and visualization, and a high-level programming language.
On Rivanna, R is available through modules, with more than one version usually available.
module spider R
Rstudio is also supported through its own module. You must first load a version of R
module load R/3.4.0
module load rstudio
Once you have developed your script, you can submit it to the compute nodes with a SLURM script similar to the following:
#!/bin/bash #SBATCH -n 1 #SBATCH -t 01:00:00 #SBATCH -o myRprog.out #SBATCH -p standard #SBATCH -A mygroup module load R Rscript myRprog.R
R can be run in parallel. Contact email@example.com for consulting in optimizing and parallelizing your scripts.
This is a SLURM job command file to run a parallel R batch job using the Rmpi or parallel packages.
#!/bin/bash #SBATCH -n 2 #SBATCH --ntasks-per-node=10 #SBATCH -t 00:30:00 #SBATCH -o myRprog.out #SBATCH -p parallel #SBATCH -A mygroup module load gcc module load openmpi module load R srun Rscript myRprog.R
