Or can I include in the vignette the command to install from github  (using devtools), and then that will build?

You definitely do not want to install packages when running a vignette.

Given that ggfortify has been archived
(https://cran.r-project.org/web/packages/ggfortify/index.html), I'd
recommend using a different package (maybe broom?).

> 3. On a remote build, my vignette is likely to fail to build.  That is because the vignette downloads a large amount of data in many requests, and if for any reason any one of the downloads fail or times out, the vignette build will fail.  As above, will this cause the entire submission to fail, or just the vignette to fail?  And is there anyway to provide a pre-built vignette in the submission?

You shouldn't be downloading data in a vignette. Can you make a
separate data package that just bundles the data?
