Programming Details
R is a programming language and software environment for statistical analysis, graphics representation and reporting.
R is freely available under the GNU General Public License, and can be loaded as a module on Viper (with Linux), Windows (PC) and Mac.
Programming example
x <- c(151, 174, 138, 186, 128, 136, 179, 163, 152, 131) y <- c(63, 81, 56, 91, 47, 57, 76, 72, 62, 48) # Apply the lm() function. relation <- lm(y~x) print(relation)
Modules Available
The following modules are available:
- module add R/3.4.1
Batch Mode
The SLURM batch file would typical look like the one below, in this case it would be named 'rscript.job'.
#!/bin/bash #SBATCH -J compute-single-node #SBATCH -N 1 #SBATCH --ntasks-per-node 1 #SBATCH -D /home/pysdlb/CODE_SAMPLES/R #SBATCH -o %N.%j.%a.out #SBATCH -e %N.%j.%a.err #SBATCH -p compute echo $SLURM_JOB_NODELIST module purge module add R/3.4.1 export I_MPI_DEBUG=5 export I_MPI_FABRICS=shm:tmi export I_MPI_FALLBACK=no Rscript r.rsc
To run this on the cluster you would need to invoke the command sbatch rscript.job
Interactive Mode
The program is interpreted by the R runtime program, so compilation does not apply here.

Libraries
To show the libraries included type ( within R ) the command : library()
Packages in library ‘/trinity/clustervision/CentOS/7/apps/R/3.3.0/lib64/R/library’:

Installing Additional Libraries
If you need an additional library installed that would be used by more than just yourself, contact the Viper team on help@hull.ac.uk with the details of the library and the version of R you require it for.
Alternatively, you can install a R library into your own personal library. Within R run the install.packages command with the package you wish to install.
> install.packages("R.matlab")
Warning in install.packages("R.matlab") :
'lib = "/trinity/clustervision/CentOS/7/apps/R/3.3.0/lib64/R/library"' is not writable
Would you like to use a personal library instead? (y/n) y
Would you like to create a personal library
~/R/x86_64-pc-linux-gnu-library/3.3
to install packages into? (y/n) y
