I am using rstudio 1.4.904. Reviewing the installed packages, I find that several of them are installed twice in different folders and of different versions. Two of those folders, / usr / lib / R / library and / lib / R / site-library have root as owner and user, the other folder / home / hugo / R / x86_64-pc-linux-gnu-library / 4.0 has as owner and user hugo.
When from RStudio I try to remove a package located in the root folders, the command is executed without providing an error message, but the package remains in those folders.
I can remove the existing duplicate packages from the root folders from the command line, but I don't know if RStudio has its own database of installed packages, because if this is the case, it would be generating a problem for RStudio.
My question is: how can I remove duplicate packages from folders owned by root? In my opinion, in the R installation, packages should only be stored in the root folders, if you are working on a multi-user computer or on a server. In the case of a computer with only one user, the installation of R and RStudio should only place in the root folders, the executables and minimum packages necessary for R and RStudio to run.
BUT beware removing packages from the System library as you may end up with a non-functioning R version and will need to re-install from scratch.
I ran rstudio as administrator and it uninstalled the old version of a package. Thanks for your suggestion!

Have you tried running RStudio with system administrator privileges?
Thanks for your reply. The problem is that in RStudio the packages are not removed when they are in a folder that belongs to the system administrator (root).
This is the command in RStudio:
This is the result when the command ls -al / usr / local / lib / R / site-library | egrep 'd? plyr' on the ubuntu 20.04 command line:
~/RStudio/R_tutorial$ ls -al /usr/local/lib/R/site-library | egrep 'd?plyr'
drwxrwxr-x 7 root staff 4096 feb 22 2020 dbplyr
drwxrwxr-x 8 root staff 4096 jul 8 17:48 plyr
As can be seen, the dbplyr package has not been removed.
The question is: how can a package located in a folder belonging to the system administrator be removed from RStudio?
