[R-pkg-devel] consider running tools::compactPDF(gs_quality = "ebook")

[Juhee Lee]

Dear all.

I checked my package on win-builder, and got this message:

* checking sizes of PDF files under 'inst/doc' ... WARNING
  'gs+qpdf' made some significant size reductions:
     compacted 'vignette.pdf' from 541Kb to 234Kb
  consider running tools::compactPDF(gs_quality = "ebook") on these files


But, I run R CMD build --compact-vignettes="gs+qpdf", and

I installed gs and qpdf on my system.

How can I solve this problem?


Best regards


Juhee Lee.
