Hi everybody,
I am including some C code in R program using the .C interface.
I would like use a C subfunction calling by C void function.
/double essai (double Px[], int tailleP)
{
Rprintf ("I print Px %d\t", Px[1]);
return 57;
}
void test_essai (double *Px, int *tailleP, double *res)
{
*res = essai(*Px, *tailleP);
This line is wrong. Try:
*res = essi(Px, *tailleP);
Note that double *Px and double Px[] are basically different ways to
say pretty much the same thing. At least in C. Not in C++ or many
other languages. But further discussion would be even more off topic.
}/ This program doesn?t work. When I compile it, I have the following error : ?In function ?test_essai : - Error: incompatible type for argument 1 of ?essai? - Note : expected ?double*? but argument is of type ?double? ? Does anyone have solution ? Thank all, Elie
