My bad. I had by oversight mixed return types and within-function types. If
you do it properly it works with either std::vector<int> or IntegerVector, as
it has for a long time.
Better version below.
Dirk
#include <Rcpp.h>
using namespace Rcpp;
// [[Rcpp::export]]
std::vector<int> test1(){
std::vector<int> a;
a.push_back(1);
a.push_back(2);
a.push_back(3);
return a;
}
// [[Rcpp::export]]
IntegerVector test2(){
IntegerVector a(3);
a[0] = 1; // push_back() not rec'd on Rcpp vectors
a[1] = 2;
a[2] = 3;
return a;
}
