I think it makes more sense for most users to have a global library (as you call it), rather than put the library under the current installation. I have been doing that for years, and it saves a lot of trouble.
When I have helped people learn R, the need to copy the library when updating is a regular source of confusion and questions. Many users are not particularly computer-savvy. Given that, it would seem desirable for the R installation to default to a global library location. ______________________________________________ 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.
