disregard previous question

Maybe sending the email to the lists jogged my brain (you know how
that is), but I finally figured out what I was banging my head
against.

In the R internals header file, I was reading

#define INTEGER(x) ((int *) DATAPTR(x))

whcih is what I hacked together in CL.  I didn't that later in the
same file, it redefines INTEGER as a function:

int *(INTEGER)(SEXP x);

which is what I needed to be using.

Cheers,
