Dear all,
I am reading the Rcpp book Chapter 7 - Modules
The first example provide a C++ function
## C++ function
double norm( double x, double y){
return sqrt(x*x + y*y);
}
## Simple wrapper function
using namespace Rcpp;
RcppExport SEXP norm_wrapper(SEXP x_, SEXP_y){
double x = as<double>(x_), y = as<double>(y_);
double res = norm(x,y);
return wrap(res);
}
So, I have these two functions. But, I am lost, what should I do now?
The goal is make the function norm available in R.
Probably, this is a very basic question, so if anyone know some material on
the internet that explain the missing parts here, please let me know.
Thank you.
