You could try following the posting guidelines, which suggest this 
question belongs in the R-devel list, rather than R-help.  Nevertheless, 
an answer below.

Why?  You only call package.skeleton once in the life of your package.  
You will be making hundreds of other changes to the package.  What's 
wrong with making this one?

If you want to know how package.skeleton decides whether to create a 
data folder, just look at its source.
