Also, consider using the rappdirs package to write to a location that follows
standard practice on each platform.

I you *prompt* the user about writing, i.e., ask them explicitly if <directory>
is fine and only if "yes", you write there, otherwise try to write to tempdir()
then your package is fine, otherwise it is not, i.e, "not okay" according to
many, even if *not* on CRAN..
Best,
Martin
