I was looking through the cheat sheet. It's nice. There are a few
things in it that I can't find in the documentation though. Where would
one find a description? (I can guess, but that may be dangerous).
R_Naint (I don't see quite how this differs from using NA_INTEGER to
set a result)
R_PreserveObject, R_ReleaseObject (Advantages/disadvantages wrt PRESERVE?)
The last is the most interesting to me.
