Dear Berwin, thank you for your help.
On my system, after "sudo apt-get install r-base r-recommended", it says :
[..]
The following packages have unmet dependencies:
r-recommended : Depends: r-cran-kernsmooth (>= 2.2.14) but it is not going
to be installed
Depends: r-cran-mass but it is not going to be installed
Depends: r-cran-class but it is not going to be installed
Depends: r-cran-nnet but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Although these packages seem to be well installed ..
