This leaves all the additional packages in the library folder (2) I reinstalled the new version into the same folder structure. The problem might be that some 1.7.1 packages might be different from 1.8.0, so it might be safer to reinstall them from CRAN.

If I install R 1.8.0, will I have to reinstall all those packages? Is there a way that I can upgrading R without losing old packages? Thank you. wz ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
