How to uninstall R and RStudio with all packages, settings and everything else?

问题

I messed up something and there is a problem with tidyverse. Tried to find a solution but spend lots of time without result.

How to uninstall R and RStudio with all packages, settings and everything else on Windows. I tried to uninstall through Windows uninstall menu and after I installed R and RStudio again same packages appeared as they were installed before. How can I erase everything related to R and RStudio so I be able to make a fresh install?

回答1:

1. Uninstall R and RStudio from Windows "Programs and Features" menu.

2. Delete everything in folders that was shown after running .libPaths() in R.

3. Delete everything in c:\Users\%USERNAME%\AppData\Local\RStudio-Desktop\

4. Install R and after Rstudio.

All packages where deleted and I think all Rstudio settings too.
