Hi Nick,

Thanks for providing an example that doesn't seem to depend on external

It's probable that there aren't many extRemes users on R-help, but if
you contact the maintainer of extRemes (run maintainer('extRemes') to
get their name and address), you might get help that way.

If you interrupt it there, backtrace() will point you in the direction
of seemingly endless loop. You can also set options(error = recover)
and get a debugger prompt at the point where you interrupted the code
or in any other frame. See ?browser and RShowDoc('R-lang') part 9
"Debugging" for more information.

I'm afraid it's easier for you to answer this question. It should be
possible to install R on computers even without administrator access.
Can you reproduce the issue with
https://cloud.r-project.org/bin/windows/base/old/4.0.4/ on your own
laptop or https://cloud.r-project.org/bin/windows/base/old/4.0.5/ on the
university-issued one?
