Thanks, Brian, I was away traveling/away from Internet and all hell breaks lose :) [more precisely Fortran broke for some reason].

Stephen,
in the case of rioja it is really a bug in your code - you have to check the result of require() or "depend" on vegan. "Suggests" means that your package works without those packages but can have improved functionality with them. In your case the example breaks if you don't have vegan - thus the package doesn't really work without vegan. (As of why vegan is not there that is my problem ;)) Thanks for the report, though.

Cheers,
Simon
