I would actually go a step in the other direction: per project libraries. For example by adding a .Rprofile file to your project directory. This ensures that everybody working on a project uses the same version of the packages (even on different machines e.g. on shared folders).
This can give issues when a new version of R arrives, but that is usually easy to solve. Either hard code the path to the old R-version or decide to update all packages in a project to the new R-version (and test that everything is still working ok).
We have the most often used packages installed centrally on the server/network, so I actually usually end up with a mixture of central, personal and project libraries. Theory vs practice.

Hi Gene, "It's complicated". (Not really, but listen for a sec...) We need to ship a default policy that makes sense for all / most situations. So - users cannot write into /usr/local/lib/R/site-library -- unless they are set up to, but adding them to the 'group' that owns that directory - root can (but ideally one should not run as root as one generally does not now what code you might get slipped in a tar.gz); but root can enable users - so we recommend letting (some or all) users write there by explicitly adding them to an appropriate group. Personally, I do not think personal libraries are a good idea on shared machines because you can end up with a different set of package (versions) than your colleague on the same machine. And or you running shiny from $HOME have different packages than shiny running as server. And on and on. Other people differ, and that is fine. If one wants personal libraries one can. I must have explained the reasoning and fixes a dozen times each on r-sig-debian (where you could have asked this too) and StackOverflow. At least the latter can be searched so look at this set: https://stackoverflow.com/search?q=user%3Ame+is%3Aanser+%2Fusr%2Flocal%2Flib%2FR%2Fsite-library Happy to take it offline too, and who knows, we even get to meet for a coffee one of these days. Hope this helps, Dirk
