[R] cacheSweave / pgfSweave driver for package vignette

[baptiste auguie]

Dear list,


I wish to use a specific driver to process an sweave document in the
inst/doc directory of a package. Specifically, I would like to use
either cacheSweave or pgfSweave to speed up the creation of the
vignette which requires lengthy computations. The same request would
also apply to the highlight driver, to provide syntax highlighting of
R chunks.

In "writing R extensions" I see that during R CMD BUILD Sweave is run
first, then optionally a makefile can be used to process any other
files. It doesn't seem to leave room for a choice of Sweave engine, as
far as I understand. One option I am thinking of is to change the
extension of the source file to something like .Rnw2 so that Sweave
ignores it altogether, and then use the appropriate command in a
makefile.

I have no experience in writing makefiles, so I'm hoping someone would
already have solved this issue and could provide some advice.

Sincerely,

baptiste
