Dear all, Thanks for all responses and recommendations!
My installation returns the same as reported by Karl Schilling; that is only 1 library path on "C:/Program Files/..." https://www.mail-archive.com/[email protected]/msg271486.html Based on everything I have read I believe the behavior I reported is due to the 'Last modified' / .builtData that apparently changes on the repository every day, although the version numbers of packages are not changed (as reported by Jinsong and Dirk). https://www.mail-archive.com/[email protected]/msg271493.html Obviously, this is something that I cannot solve, but I am happy I understand the root of the cause. Thanks, Guido PS: since I only receive the 'Daily Digest' of the R mailing list, I hope my mail will be properly placed in the archive. And this also the reason I above included URLs to earlier responses. ______________________________________________ [email protected] mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide https://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
