[Rd] Packing of data files in packages

[Kjetil Brinchmann Halvorsen]

Hola!

I am writing a package with some large data files, so it would be good to
use the feature of zipping data.

However, I use .R files to read in the data from one (sometimes more)
files, so Rcmd build --zip-data
gives a package which does'nt work. How should I do it, is it better ti
zip each data file individually and use the functions to read from 
zipped files, or are there some other solution?
Did'nt find anything in "Writing R extensions".
