Thanks a lot for your help Dirk.
That's while searching for a way to run your solution that I found one witch worked. I found a tutorial which told me to execute the following command :
 sudo add-apt-repository ppa:marutter/rrutter
 sudo apt-get update
 sudo apt-get install r-base r-base-dev
It worked ! Installing r studio after was no problem.
