Tim,
Three distinct errors:
- no wrapping function, so sourceCpp() was the wrong paradigm
- no inclusion of Rcpp.h so types unknown (agem)
- wrong calling convention for runif(), cannot be empty.
The following compiles, it may still be nonsensical.
Dirk
// [[Rcpp::depends(BH)]]
// [[Rcpp::plugins(cpp11)]]
#include <Rcpp.h>
#include <vector>
#include <boost/geometry.hpp>
#include <boost/geometry/geometries/point_xy.hpp>
using key_type = boost::geometry::model::d2::point_xy<double>;
using range_type = std::vector<key_type>;
// [[Rcpp::export]]
void foo() {
range_type data;
data.reserve(1e6);
for (int i = 0; i != 1e6; ++i)
data.emplace_back(R::runif(0,1), R::runif(0,1));
}
