You have to coerce to numeric yourself if that's what you want. Eg in the R
code, as.numeric(1:12) rather than 1:12. Or check the type first in C with

that the two do different casts; they both point a fixed offset into the R
ction from C. How do you
deal with SEXPs?

The C wrappers are there to align the linking conventions expected by the
Fortran compiler (usually subroutine/function foo has its entry point in the
object file indicated by a symbol foo_, but it depends on the platform) to
that of the C compiler. (The C compiler just uses the function name.) The
