Rolf,
I think it may help to read-up on dpkg and apt. Instead of 'whereis' do dpkg -l r-base-core to see the content of that package. Use apt-cache policy r-base-core to see what the package cache says about where it gets the package from. And so on. Also type -p R which R will tell where your system thinks R comes from. If you install R 3.5.2 you should not see R 3.5.1. These aren't really R issues. The package management system can be pure source of joy. Something seems to have gotten crossed at your end but we cannot tell what.
