I believe this is specific to Windows, which you have nowhere
mentioned. And the preferred way to make a binary package there (see
'Writing R Extensions') has long been R CMD INSTALL --build and not R
CMD build --binary. So this is really a question about R CMD INSTALL
--build: --use-zip-data is an option to 'INSTALL' and not to
There have been substantial recent changes in the R CMD utilities and
more will be coming in R 2.12.0. So I am going to answer this as if
it were about R 2.11.x on Windows, but it would have been courteous to
let us know (as the posting guide asks).

In 'Writing R Extensions' I see in section 1.1.1:
The optional `ZipData' field controls whether the automatic Windows
build will zip up the data directory or no: set this to `no' if your
package will not work with a zipped data directory.
That seems to be the answer to your question.

That's not really what the 'data' directory is for: if you want to
provide data in any form other than for use by data(), please use a
different subdirectory ('extdata' or 'datasets' are two I have seen
used). Again, see Writing R Extensions section 1.1.5.
