Hi, Instructions for authenticating the cran repositories are here: http://cran.r-project.org/bin/linux/ubuntu/
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 R. 2) You can also install packages using the regular install.packages() in an R session. Hope that helps, -Ista On Wed, Oct 14, 2009 at 10:11 PM, robstdev <robst...@gmail.com> wrote: > Installing R on Ubuntu 8.10, > ( using sudo apt-get install r-base , and using one of the cran sites > (cran.cnr.berkeley.edu)) > > the installation process says something about not having some gpg > public key and > "are you sure you want to download non-authenticated stuff [y/n]" (to > which I answered yes). > I'm assuming this warning can be ignored? > > Also: even though the Ubuntu install and online update did a GCC > install the other day, the R installation did an update of some GCC > files, which I thought was odd.
