Since this has come up already: It is a good idea to re-install all packages for a minor-version increment of R, e.g. 2.5.1 -> 2.6.0 (it is major.minor.patchlevel). This is most easily done by
> update.packages(checkBuilt=TRUE, ask=FALSE) However, if you don't want to do that yet, be aware that - Certain S4-using packages must be reinstalled, and using old versions can make R malfunction. I believe these are Brobdingnag, Matrix, NADA and kappalab. - Any S4 package that makes an existing function S4-generic will grab that function as it existed in the version of R under which they were installed. If it has changed, there is potential trouble. - Packages that create or change character strings at C level will have needed to be updated for R 2.6.0 (and some have not yet been). Using such a package can in principle result in other character data being changed (since most character strings now share storage). -- Brian D.
