[R-pkg-devel] compact vignettes

[Richard M. Heiberger]

I need some help on the compacting of pdf files in the inst/doc/ directory.
When I use the --compact-vignettes option, as in
  R CMD build --compact-vignettes microplot
the relevant pdf filesize drops 76 bytes.

The CRAN pretest makes it drop in size by 270 kilobytes

What incantation am I missing?

Thanks
Rich
