Re: [R] R-update - what about packages and ESS?

Thanks for the answers so far.

I have to go through this with my system administrator.

The system is slackware linux.

I don't really understand what "does not wipe out" means. Certainly, the packages are not deleted from the hard disk, but...

Am I right that I should expect it as standard behaviour that all previously installed packages are found if R is updated in a straightforward manner (using "make install", say)? Or is the opposite true that I definitely should not expect it? (And is there any standard solution for this else than installing all packages again?)

That's not really enough because I want to have them accessible to students as well. Furthermore, the sysadmin may develop kind of a "the whole R-thing is crap"-attitude if I can't come up with a solution preventing new installation of all packages, and I don't really want that. So I'm rather not interested in discussing solutions which involve installing all packages again (I know that this is possible).
