Examining the packages installed by R I find 73 packages on my computer that only differ in their version, but that the old versions cannot be uninstalled because they are in the root folders: "/ usr / local / lib / R / site-library".
In all Linux forums it is discouraged to run programs other than those of administration as root.
Consequently I think that on the initial installation of R, only the minimal programs and scripts should be installed in the root folders for R to run, and all other packages should be installed in the / home / "username" folder.
Is there a way to install R like that?
