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

[Yihui Xie]

Yes, I also wish Sweave could give us more flexible options, e.g. it
should not be difficult to free the graphics device specification as
an R function (pdf, png, CairoPDF, ...) instead of just letting us set
pdf=T/F and eps=T/F.

If we don't want to hack the Sweave code, we may also rewrite it as a
package. This has been in my mind for a long time.

Regards,
Yihui
