My solution is similar to Ben's solution. Except that the code for creating the data is in the vignette. The chunk only runs when the data is not available. The trick is to pass code to the eval argument instead of a fixed TRUE or FALSE. See https://github.com/ropensci/git2rdata/blob/bad8a4cf42049faa72a04b202c5a4dfc233b4046/vignettes/efficiency.Rmd#L293 for an example.
