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).

mkNamed
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.
