After I changed to Version R version 4.0.0 (2020-04-24) -- "Arbor Day" on my MacBook running Mac OS 10.13.6, I lost all my loaded libraries. Also, the package installer can not contact CRAN libraries either for binaries or sources, to replace the missing loaded libraries. The package installer can contact "BioConductor", however. I am now specifically looking for "HURDAT" and "lmtest", which were on CRAN but not "BioConductor". - - Roger Coppock (rcoppock at cox.net)

It is very well maintained by the RStudio folks. Duncan Murdoch
Recently a message appears when I try to view the index of the CRAN library.

The message at that URL reads: CRAN mirror restricted to UC Berkeley The CRAN mirror at UC Berkeley's College of Natural Resources is no longer available to off campus users and has been removed from the CRAN mirror list. The load on our server was too much. Berkeley folks can continue to access the mirror from on-campus networks or from within the VPN. The rest of the R community: Sorry, but you'll have to please choose a different CRAN mirror. --Chris Ryan Roger Coppock wrote:> Recently a message appears when I try to view the index of the CRAN library. > > Warning: unable to access index for repository http://cran.cnr.Berkeley.edu/bin/macosx/contrib/4.0: > cannot open URL 'http://cran.cnr.Berkeley.edu/bin/macosx/contrib/4.0/PACKAGES' > > Does the CRAN library have the Coronavirus? > > - - Roger Coppock (rcoppock at cox.net) > >> On May 1, 2020, at 9:24 AM, Roger Coppock <rcoppock at cox.net> wrote: >> >> After I changed to Version R version 4.0.0 (2020-04-24) -- "Arbor Day" on my MacBook running Mac OS 10.13.6, I lost all my loaded libraries.

a) You will help yourself and those who you attempt to communicate with if you
learn the terminology correctly as described in the RcInstallation and
Administration manual (e.g. RShowDoc("R-admin") or
https://cran.r-project.org/doc/manuals/r-release/R-admin.html):
1) Packages are collections of functions and documentation.
2) Libraries are the directories _on our computers_ in which we keep packages
that we want convenient access to.
3) Repositories are directories of packages on internet servers from which we
typically retrieve packages that we want to keep in our libraries.
b) There are many web servers that mirror the contents of the CRAN repository.
They are operated as volunteer contributions to the R community. You have
referenced one of them in your error message.
c) If you use your web browser to visit the URL you reported in your post then
there is a message returned that explains what happened and offers a suggestion
as to next steps you should take.
