R and Rscript¶
Various versions of the R environment are available on CSD3. The latest
version, R 3.5.2 is available either as
r-3.5.2-gcc-5.4.0-jqs2rxd. The former is a vanilla R install with no
special options, whereas the latter is linked against the linear algebra
library openblas and may provide substantially better performance.
R can be run interactively by simply calling
R, which will give a standard
R shell. This can be used for testing or setting up larger runs. However for
use inside the job scheduler it will generally be more effective to record the
R script in a file
analysis.R and call it from inside a slurm batch script
Rscript analysis.R. For more examples of how to use slurm and write an
appropriate batch script please see Running.
