You are mixing up two different things. The .libPaths() function returns paths where R searches for R packages.
Rtools is not an R package, it is a collection of utilities and support files to run in Windows.
For Rtools to be found, you need to add it to the Windows PATH variable, not to .libPaths(). You can see the current value of PATH by running this in R:
Sys.getenv("PATH")
This will give a long string variable with various directories separated
by semicolons. You want to make sure it contains the Rtools40
executable directory (typically "C:/Rtools40/usr/bin", though for you it
might be "\\\\gold/home/ndw003/reichmjs/MyDocs/R/rtools40/usr/bin"). If
it doesn't (which would cause has_rtools() to fail, so I'll assume it's
not in yours) you can add it temporarily using
Sys.setenv(PATH = paste(Sys.getenv("PATH"), "\\\\gold/home/ndw003/reichmjs/MyDocs/R/rtools40/usr/bin", sep = ";"))
For a permanent addition you need to edit the system PATH setting. You should probably ask an admin to do that for you.
