Open a terminal and type

sudo aptitude update
sudo aptitude search r-cran

The packages marked with an "i" on the leftmost column are installed.
Those marked with a p are not installed.

sudo aptitude search r-cran will give you the list of packages
available through the apt package management system. Additional
packages are listed on the CRAN website, and can be installed using
install.packages("PackageName") at the R command line.

Depends on what your're used to. I've been using Ubuntu long enough
that sudo is second nature...
