Use environment modules with qsub script

If you want to use the modules command within a script that you want to submit with qsub
you need to source /usr/local/Modules/current/init/bash.
An example script that would submit a R v3.2.3 job would look like this:

#!/bin/bash
#$ -S /bin/bash
#$ -q all.q
#$ -N my_first_job
#$ -l h_vmem=1G
#$ -cwd
#$ -j Y
#$ -V
#$ -m be
#$ -M email@address.lumc

. /usr/local/Modules/current/init/bash

module load R/3.2.3

R CMD BATCH test.R
