Let me add a couple more comments about this. In case you can include
the data file, this has the benefit that you can use it in your tests
too (I've seen that you simply skip_on_cran and skip_on_travis). Also,
I've seen that you write files in one vignette. Note that you should
use the tempdir() for that.
