I am failing to get compactPDF to make any change to a pdf file
that, a/c to the message from the CRAN upload site, can be very
substantially compacted. Any ideas what may be wrong?
I have also tried recreating the pdf file. I also tried
R CMD build --resave-data --compact-vignettes DAAG
The data files compact alright (but I get the 'significantly better compression'
warning message that might suggest that this is not happening), but the pdf
file appears to go into the package unmodified.

Message from the CRAN upload site:
* checking sizes of PDF files under ‘inst/doc’ ... NOTE
‘gs’ made some significant size reductions:
compacted ‘rockArt.pdf’ from 680Kb to 58Kb
consider running tools::compactPDF(gs_quality = "ebook") on these files
