I meant that perhaps R-Forge and CRAN could *automatically* do the 
compaction.

I *do* run R CMD build on my machine with options
--compact-vignettes=qpdf --keep-empty-dirs --resave-data

giving the log info:

* checking for file 'C:/Documents/workspace/heplots/DESCRIPTION' ... OK
* preparing 'heplots':
* checking DESCRIPTION meta-information ... OK
* installing the package to re-build vignettes
* creating vignettes ... OK
* compacting vignettes and other PDF files
* checking for LF line-endings in source and make files
* checking for empty or unneeded directories
* looking to see if a 'data/datalist' file should be added
* re-saving image files
* building 'heplots_1.0-9.tar.gz'

However:
(a) the heplots_1.0-9.tar.gz source package is built outside of the 
workspace source tree I sync with R-Forge
(b) when I examine the heplots_1.0-9.tar.gz source package, the file 
heplots/inst/doc/HE-examples has
not been modified in size.
So, I still don't know how to correct this on my end.
