I am a little remote here, both mentally and physically. What I might do here
in the case of your long-running vignette, and have done in about half a
dozen packages where I wanted 'certainty' and no surprises, is to render the
pdf vignette I want as I want them locally, ship them in the package as an
included file (sometimes from a subdirectory) and have a five-or-so line
Sweave .Rnw file include it. That works without hassles. Here is the Rnw I
use for package anytime
-----------------------------------------------------------------------------
\documentclass{article}
\usepackage{pdfpages}
%\VignetteIndexEntry{Introduction to anytime}
%\VignetteKeywords{anytime, date, datetime, conversion}
%\VignettePackage{anytime}
%\VignetteEncoding{UTF-8}
\begin{document}
\includepdf[pages=-, fitpaper=true]{anytime-intro.pdf}
\end{document}
-----------------------------------------------------------------------------
That is five lines of LaTeX code slurping in the pdf (per the blog post by
Mark). As I understand it R.rsp does something similar at the marginal cost
of an added dependency.
Now, as mentioned, you can also 'conditionally' conpute in a vignette and
choose if and when to use a data cache. I think that we show most of that in
the package described in the RJournal piece by Brooke and myself on drat for
data repositories. (We may be skipping the compute when the data is not
accessible. Loading a precomputed set is similar. I may be doing that in the
much older never quite finished gcbd package and its vignette.
Hope this helps, maybe more once I am back home.
Cheers, Dirk
