Re: [R] vignettes: .png graphics or pre-compiled .pdf

[Michael Friendly]

Thanks, Yihui
Your solution, for png(), only looks dirty because you had to hack the 
Sweave code.
It would be nice to have png() support included directly.

Hi Michael,

I have a dirty solution as attached to use png() for Sweave.

HTH.

In a package I'm working on there is a vignette with a number of graphs that
result in huge .pdf files, so
the .pdf for the vignette is around 17 Mb.  If these graphs are converted to
.png, and the .tex file
is compiled with pdflatex, the resulting .pdf is ~1 Mb.

I'm reluctant to put the .Rnw file into the package as is, generating the
huge .pdf for the vignette.
I first tried installing the smaller .pdf file in the package by itself (no
.Rnw)
together with a file inst/doc/index.html as recommended
in 'Writing R Extensions.'  However, when the package is installed,
vignette() can't find it

      
vignette(package="Guerry")
        
no vignettes found
      
vignette("MultiSpat")
        
Warning message:
vignette 'MultiSpat' *not* found

Alternatively, is there a way to generate .png graphs from the .Rnw file so
that those are used in building
the .pdf for the package?  AFAICS, \SweaveOpts{} offers only the choices of
eps/pdf = {TRUE/FALSE}.
