Why does assert not work here?

Question

Here is the code:

#include 
#include 
#include 
#include 

using namespace Rcpp;


// [[Rcpp::ex         


        

Answer 1

The problem is solved by using throw instead of assert, Rcpp will actually put things in a proper try-catch block, which is super nice.

#include 
#include 
#include 
#include 

using namespace Rcpp;


// [[Rcpp::export]]
double eudist(NumericVector x, NumericVector y) {
    int nx = x.size();
    int ny = y.size();
    Rcout << nx << '\n' << ny << std::endl;

    if(nx != ny) {
        throw std::invalid_argument("Two vectors are not of the same length!");
    }

    double dist=0;
    for(int i = 0; i < nx; i++) {
        dist += pow(x[i] - y[i], 2);
    }

    return sqrt(dist);
}
