[R] CRAN library down? - UPDATE

[Roger Coppock]

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?

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".
