[Rd] returning an empty list.

[James Bullard]

I would like to return an empty list from a C function. This I would do as:
if (file.exists()) {
   /* do something */
}
else {
   SEXP empty_list;
   PROTECT(empty_list = NEW_LIST(0));
   UNPROTECT(1);
   return empty_list;
}
The PROTECT, UNPROTECT lines seemed like overkill to me, but as far as I 
understood the documentation this seemed like the correct usage. It 
seems like I could really just do the following:

return NEW_LIST(0);
but I thought I'd better ask first. Thanks in advance, I hope I did not 
miss something in the documentation which describes this.

Thanks, jim
