HPC Examples


You don’t need to be in an interactive session to view and save figures. In a batch script you can save your figure to a specified directory (the default is your working directory), give it a custom name, control your image quality and dimensions, and choose your output format (e.g., pdf, png, jpg, etc.). An example is included below.

Submission Script

To run your R script as a batch job, use Rscript instead of R which is used for interactive sessions.

#SBATCH --job-name=R-Plotting-Job
#SBATCH --ntasks=1
#SBATCH --nodes=1 
#SBATCH --time=00:01:00   
#SBATCH --partition=standard

module load R/4.0.0
Rscript example.r

R Script

print ("In R Script. Plotting...")
x <- seq(-pi,pi,0.1)
plot(x, sin(x))
