Edzer,

you can think about

1. if it is possible to include some objects derived from the data 
rather than the whole data, but that contradicts the aim of the package, 
as far as I understand.

2. just provide the pdf rather than the Rnw and calculate the vignette 
for yourself only, but this way the users cannot run the code, if that 
is relevant.

3. ask CRAN maintainers not to check the vignettes of your package. This 
is not standard and I am a bit reluctant to suggest exceptions, but 
since most (if not all) of us have code in place to easily omit vignette 
checks for particular packages this might be the most appropriate 
solution here.


Kurt is on vacations, so it may take a while to get his response on 
this. CCing Brian Ripley who runs checks for CRAN but does not read CRAN at ...
