Hello again,
I hope I don't disturb you too much. I have again a small question. I
haven't seen the answer on your vignette, maybe this is not possible.
Here's what I would like to do :
/double Foo(double x, double a1, double a2) {/
/return f(x,a1,a2);/
/}/
/
/
/NumericVector myVec;/
/
/
/sapply(myVec, Foo( ……, a1, a2)); // This is the line not working/
In every example I saw, Foo (in the example, it's sometimes square)
could only have one parameter (and in my case I have many parameters).
Is it possible ? Am I missing something ?
Thank you very much (again) for your time,
Have a nice evening/week-end,
Julien
So to elaborate on my answer, since you did not report back, something
like this works for me:
#include <Rcpp.h>
using namespace Rcpp ;
double fun(double x, double y, double z) {
return x + y + z ;
}
// [[Rcpp::export]]
NumericVector mapply_fun(NumericVector x, NumericVector y, NumericVector z){
return mapply(x, y, z, fun ) ;
}
So mapply'ing fun over x, y and z. works for 2 or 3 objects for now.
