[R-pkg-devel] Problem compressing vignettes for CRAN

[Michael Dewey]

I am trying to update my CRAN package metap. When I ran a final check on 
winbuilder I got the warning

* checking sizes of PDF files under 'inst/doc' ... WARNING
   'gs+qpdf' made some significant size reductions:
      compacted 'compare.pdf' from 498Kb to 243Kb
      compacted 'plotmetap.pdf' from 349Kb to 91Kb
   consider running tools::compactPDF(gs_quality = "ebook") on these files,
   or build the source package with --compact-vignettes=both

But I did use the option --compact-vignettes=both when I built the tarball.

I do have gs installed but not qpdf. I built the package under Windows 
if that is relevant.

Any suggestions?
