I would recommend copying the snippet/minor function into your own
code, with attribution/citation (and, as a courtesy, e-mailing the
maintainer of the package to let them know).
The only disadvantage I can think of in this approach is that you
won't automatically benefit from bug fixes or other improvements in
the upstream code.
