Problem installing certain packages...

First post, excuse me if it might prove unclear.

So, been through some posts trying to see whether this had a solution or not, and I couldn't find anything useful.

Error Information:

can't load ggplot2, markdown, and others... also can't update some others like haven or mnormt - well, that sums it up

Steps taken so far
< library("ggplot2")
Error: package or namespace load failed for ‘ggplot2’ in get(Info[i, 1], envir = env):

System Information:

  • R v4.0.0
  • RStudio v1.2.5033
  • Win 10 Home, OS v18363.836
  • and lots of packages

Also:

tried restarting session, and started with admin rights afterwards.. no luck either

tried updating rlang and no luck

tried updating rcpp and I'd bet you know the outcome

is it necessary to reinstall R?

Thanks in advance

Can't believe it, but yeah... I wanted to avoid reinstalling, but before going nuts and after a bit of thinking out loud in not the nicest language I backed up everything and saved a noteblock with all packages...

turns out I was using R v4.0.0 beta, and now it's the official v4.0.0.. guess that was the whole issue, although not sure on a technical level

hope this site could add another last, emergency solution... backup and reinstall the whole thing...
