Hello all! R2.2.1, W2k. When I used "update.packages()" today, R wanted to update VR, cluster and nlme packages. I did so using the Danish mirror. Everything worked as usual during update, but after closing R and trying to restart I got an error message saying that the .Rdata could not be restored. Re-installing from my downloaded .exe file cured this, but what happened and what package could have caused the problem? /CG -- CG Pettersson, MSci, PhD Stud.
