It is worth checking that the library where things were most recently
installed is the first place R looks, i.e. the first entry in
.libPaths(). Often R is installed by an administrator, and users can't
write to the main library, so when they install packages they go
somewhere else. If "somewhere else" isn't first in .libPaths(), R won't
see the new installs.

I did try installing xml2 and it appeared to complete. I will ask him to try
again and send me the output.

Seems like they should install the xml2 package before proceeding to load
whatever (tidyverse).
This kind of "dependency missing" problem tends to be a recurring problem
particularly on Windows but in general when some deeply-embedded dependency fails to load
or is removed in preparation for upgrading.

Below is some output from one of my students. I have never seen this error and
tried a few things (updating packages for one) but am at a loss to help
further. Would appreciate suggestions that I can pass along.
Here is the error. I tried an install.packages(“xml2”) which appeared to
complete but the error persists.
library("tidyverse")
Error: package or namespace load failed for ‘tidyverse’ in library.dynam(lib,
