Greetings -- I'd like to keep my R on Mac in an upgradeable way. I noticed that currently all packages I installed from R.app are in the R.framework -- are they going to be clobbered when I replace R 2.7.2 by 2.8.0? At the same time with the upgrade, I'd also like to switch to 64 bit. One good page I found about it is http://www.matthewckeller.com/html/64_bit_r_on_mac.html It suggests that packages are installed into a separate directory by doing it from command line install.packages with a lib= parameter. Now I'd like to install everything into a lib anyways, but preferably without having to specify lib= all the time -- is there a way to make my local location the default for install.packages? Also -- can the R.app be tweaked to do all this, if I want to use it with the 64 bit and local install for packages? The idea is to make upgrading R smooth -- ideally, it would do update.packages(checkBuilt = TRUE) by itself as a part of the upgrade. Are there other ways to simplify R upgrade on Mac and/or am I missing something? Cheers, Alexy

No, they will stay in the 2.7 folder. You can re-install them for 2.8 by selecting "Select packages from R 2.7" in the search field of the Package Installer and clicking on "Install Selected".

That page is dangerous and incorrect (see my earlier post about it on this list). I would advise users to be cautious about following instructions blindly, you better be sure that the person knows what s/ he's writing about. If you feel that some instructions on CRAN or the R for Mac Devel page are insufficient, say so here instead of speculating!

Several - see "At User Level" and "As defined by .libPath()" options in the Package Installer.
Also -- can the R.app be tweaked to do all this, if I want to use it with the 64 bit and local install for packages?
What do you mean by "all this"? It already supports an easy upgrade between R version and custom paths so I really don't see what you're missing. Cheers, S
