The article about precomputing vignettes has a caveat that if your vignette includes figures, you must take care to save them to the vignettes/folder. It would be nice to have an example of how to do that. I was thinking this might do the trick:

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>",
  fig.path = "vignettes/"
)

But the figure generated in the pre-compute step doesn't get moved to doc/ by build_vignettes() or to docs/articles/ by pkgdown::build_site() and the images don't show up in the rendered HTML. Do I need to just manually (or with a script) move the figures to the correct spot(s)?
