[R-pkg-devel] \donttest{} and writing outputs to tempdir()

[Jeff Newmiller]

Make examples shorter so they can run faster. Wrapping everything in donttest means that running examples() does nothing, which is counterproductive.

Techinically, vignettes are not tests or examples... but they do have the advantage that they don't have to run quickly. But that doesn't make a vignette a substitute for either examples or tests.

As for writing to the wrong place, you should probably just double check.
