We are having an issue downloading packages through R Studio Package Manager after updating to the latest version of R. We had to use R Studio Package Manager because we need to keep our data in offline environment.
We get a 404 error when trying to install. It is trying to go to the …contrib/4.0 URL and it doesn’t exist. If we
run R 3.4 it goes to the …contrib/3.4 URL and can find it just fine.
The error said: Warning in install.packages: Cannot open URL 'httpL//..../prod-cran/latest/bin/windows/contrib/4.0/hR_0.2.41.zip.
We can access the same package through R 3.4.
Thank you!
