Instructions for authenticating the cran repositories are here:
r-base comes with whatever the base R libraries are (stats, graphics
etc.). I don't know if MASS in particular is in base because I don't
use it directly.
As far as I know it's safe to ignore the warnings, but they annoy me
so I always following the instructions linked above.
The list of packages regularly updated in the cran repo are also
listed on the webpage linked above.
A couple of further tips:
1) I usually install packages with sudo aptitude install r-cran-xxx
and then make sure they are up-to date by running update.packages() in
2) You can also install packages using the regular install.packages()
in an R session.
Hope that helps,
