On a windows machine you get the same problem. Useless one uses tha same trick as Rolf suggested: don't install the packages in the default directory and set R_LIBS to that directory. Then all you need to do after an upgrade is to set R_LIBS in the new version and run update.package(checkBuilt = TRUE). Given Rolf's suggestion I suppose this trick will work on a Mac too.

But I have the ***impression*** that (on my system) by default packages get installed into ~/Library/R/2.7/library i.e. into a library inside the directory tree rooted in my login directory. I don't use this --- I've created my own library ~/Rlib and have set up an environment variable to point to it. (This works properly only if you start R from the command line; for reasons I don't understand if you start R by clicking on the icon then R doesn't know about the R_LIBS environment variable. But since all civilized people start R from the command line .....) I have no idea why youse guys' systems would eschew using ~/Library/ <whatever>. cheers, Rolf Turner ###################################################################### Attention:\ This e-mail message is privileged and confid...{{dropped:9}} ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
