Call “multi file C++ code with external libraries referenced” in R

Question

I have written a code in C++ which uses boost library and also uses multiple files. I am trying to execute the function in R.

Here is my C++ function prototype:

Answer 1

Use Rcpp instead of .Call.

Add this headers and comment to your .cpp function file:

#include 
using namespace Rcpp;

// [[Rcpp::export]]

And now in R:

 install.packages("Rcpp")
 library(Rcpp)
 sourceCpp('path to your .cpp program')

The function EulerInversions should become visible in the environment and you can call it now as any other R function
