[R] CRAN library down?

[Roger Coppock]

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".
