On Windows, I've found that it is actually better to uninstall the old version first. Uninstalling removes file associations for .Rdata and other files even if a more recent version of R is present (although perhaps there is a way to tell it not to) but this won't be a problem if you do it in the following order: > 3) uninstall the old version > 1) install the new version > 2) copy all or the libraries that you installed later from the "library" > folder > of older version to the new version > 4) do a library update in the new version Kenn ______________________________________________ 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.
