-  - install it in your ''${HOME}'' folder: <code console> +
-capello@login2:~$ mkdir Downloads +
-capello@login2:~$ cd Downloads +
-capello@login2:~/Downloads$ wget ${URL_FOR_rstudio-${VERSION}-x86_64-fedora.tar.gz} +

-</code> Doing so, you will have 16 cores on one node of the partition ''debug-cpu'' for a max time of 15 minutes. Specify the appropriate duration time, partition, etc. like you would do for a normal job. +
-    - load one of the R version supported by RStudio, for example:<code console> +
