Just to be sure: Are you running R CMD check on that freshly built
tarball or is devtools::check() involved?

- Does the R CMD build log actually show "re-saving image files" or
"re-saving sysdata.rda"?
- Have you set the BuildResaveData field in your DESCRIPTION file? This
would take precedence over the --resave-data command line switch.
- Have you tried running tools::resaveRdaFiles() on your source data
directory before building the package? Does that reduce the size of your
data files?

You'll get the NOTE when R CMD check finds that running
tools::resaveRdaFiles() on the data directory would reduce a file's size
by more than 10% with a different type of compression (if the original
size is >10KB).
Hope this helps.
