I want to incorporate a static PDF (created from LaTeX source separately
from the R package) into an R package as a vignette. One approach I found
was to use the LaTeX pdfpages package, which works fine locally and on some
but is not present in all RHub environments. Is the use of pdfpages a
viable approach? What is the set of LaTeX packages that can be assumed?
I tried using R.rsp as an alternative but it did not work for me and I
stopped trying it because I had an approach that appeared to work.
