The process that you outlined is described in the Windows R FAQ 2.8 "What's the best way to upgrade?". The same process should apply to other platforms as well, but I don't think it is in the general R FAQ. Perhaps it should.

You can keep multiple versions of R simultaneously, so this is no problem. That is: 1) Install new R version 2) Run update.packages() on old library version 3) Copy updated old library to new library location (or point new library location to old) 4) Remove old R version (and its libraries if you copied them) There are probably better ways to do this, which this message may stimulate. -- Bert ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
