[Rd] R CMD check and Suggests Packages

[Dario Strbenac]

The intention was more to have another place to make the user aware of a real-sized data package I made, since the package only comes with trivially sized data. The help examples and vignette only use the small sized data, and never the realistic dataset. I suppose it is better just to put a reference to it in the vignette and describe its availability in there.
