Hi Kjetil!

I would pack the files, as you said, and use functions to read from zipped files.

You can place the data file in the directory e.g inst/mydata.
See (writing R extension to know more about the inst directory)
After installing the package you can get the path to the mydata direcotry using the function ?system.file
