Damm... I am reading the WRE, but I am only at page 83. I start to try to
play with NAOK to early.
Anyway, exactly the same function for numeric instead of integer will give
different results:
--- 8< ------------ C code -----------
void hein2(double *a, double *b, double* c){
*c = (*a + *b);
}
--- 8< -----------------------------------
--- 8< ------------- R code -----------
.C("hein2",as.numeric(NA),as.numeric(1),as.numeric(1),NAOK=TRUE)[[3]]
[1] NA
--- 8< ---------------------------------
That's why I find the results of "hein" stranges...
