Janko,

You have to save the data objects you want into that directory in your
source package. Then when you build/install it will be there.

Regards,
Brian

Hi Dirk,

thanks for the quick reply. So all datasets, regardless if they should
be
hidden from the user, should go into /data? If that's the convention,
that's
fine with me. But the problem is that there is no data-directory in
R_HOME/library/2-11.1/mypackage after running R CMD build and R CMD
INSTALL.
I've experimented with the options --binary and --use-zip-data but
without
luck.

I think I don't understand the "optional directory" procedure in
general
yet: don't I just need to dump stuff in /data, /inst/doc, /exec etc.
and
have them "transferred" (sorry, I don't know a better word) to the
tar.gz
and eventually to the installed package?

Regards,
Janko

If in doubt, copy existing packages, preferably recommended ones:

edd at max:~/src/debian/CRAN$ find -type d -name data | sort
./boot-1.2.42/data
./boot-1.2.43/data
./car-2.0-2/data
./cluster-1.13.1/data
./effects-2.0.10/data
./fEcofin-290.76/data
./fExtremes-2100.77/data
./fGarch-2110.80/data
./fImport-2110.79/data
./fPortfolio-2110.79/data
./gdata-2.8.0/data
./gplots-2.8.0/data
./gtools-2.6.2/data
./lattice-0.19-11/data
./lattice-0.19-13/data
./latticeExtra-0.6-14/data
./lme4-0.999375-35/data
./lmtest-0.9.27/data
./MASS-7.3-7/data
./Matrix-0.999375-44/data
./misc3d-0.7-1/data
./multcomp-1.2-3/data
./nlme-3.1.96/data
./nlme-3.1.97/data
./nws-2.0.0.3/data
./rggobi-2.1.16/data
./robustbase-0.5-0-1/data
./rpart-3.1.46/data
./sandwich-2.2-6/data
./sm-2.2-4.1/data
./sn-0.4-16/data
./strucchange-1.4-1/data
./strucchange-1.4-2/data
./survival-2.35-8/data
./timeSeries-2120.89/data
./tseries-0.10-22/data
./urca-1.2-4/data
edd at max:~/src/debian/CRAN$

The vote is clearly in favour of data/ over inst/data.

Hth, Dirk
