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.
- R has versions 3.3.0, 3.4.1 and 3.5.1.
R-Studio is also provided as an interactive session on Viper for R-Studio.
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.

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/4.0.2/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
