I am trying to install R2.11 on RHEL5.3. The main code and base packages compile fine and get installed to \usr\local\R211 (which I set using --prefix). I would like to install a set of contrib packages (car, ggplot2, etc.) also to the same location. Once R is fired up, I can do install.packages() and it gets installed in ~/ R/... Is there any way of installing these packages to the main R installation. There are some packages which all of us in the group use and would prefer not to repeat for each user. (if sudo R CMD install is the way to do it, is there a way in which I can specify just the package names and have it figure out the dependencies without me having to download all the tar balls manually?). Thanks.
