I upgraded to R 3.6.2 today (macOS Mojave 10.14.6) and when I try to install any package I receive the following message:
I've tried a few different CRAN mirrors but all return the same issue. I can install from sources, but sometime this will fail if the dependencies can't be installed from source.
Looking at the URL provided, it doesn't seem like /PACKAGES directory exists. Anyone have an idea about what is going on and how to fix this?
