Uninstalling R and R Studio from the mac

How to delete R from the mac. Currently, Tidyverse package no longer works and thus I have to reinstall the R. But, I am not able to fully delete the programme as it keeps creeping back. What to do to completely uninstall R and R Studio from the mac. I can’t locate a script to remove all the things these packages installed nor able to find support from the R community. Is this documented anywhere?
