Your original question was about macro-like functions. INTEGER is
available to internal R code as a macro; it is also available as a
function. Code in packages that uses standard hearders will see the
function, which is declared as
int *(INTEGER)(SEXP x);
I have no idea why you wanted to check wh

Hi,
Thank you to Duncan Murdoch for pointing to
http://www.stat.uiowa.edu/~luke/R/barrier.html.
I have a couple of questions in this regard:

and I want to increment each element by one. I understand that
int * xIPtr = INTEGER(

Hi,
Somehow function-like macros from Rinternals.h are not defined when I
include the file.
foo.c
##

#ifndef NILSXP
#error("NILSXP")

#ifndef INTEGER
#error("INTEGER")
