If the user uses bioconductor for biology projects in R and their R library becomes corrupted you can do this command in the R prompt.
> BiocManager::valid()
At the end of this command it will present a very large R function you can call to fix the installation. Just copy and paste the section that looks like the section in green into the R intepreter and it will try and "fix" the installation.
