The whole point of using a version-dependent directories is exactly to prevent the chaos resulting from what you suggest. If you installed package at the system level then you can upgrade using the GUI: Package Installer -> Get List -> Select Packages from R 2.11 (in the search menu) -> Install Selected If you use user-local path like you mentioned above, you can always simply use install.packages(.packages(TRUE,"~/Library/R/2.11/library")) Cheers, Simon _______________________________________________ R-SIG-Mac mailing list R-SIG-Mac@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-mac
