Dear all, I created a small example that reproduces my error below. It has to
do with my use of module with .constructor<const Rcpp::NumericVector &, int>()
with Rcpp::NumericVector. I guess I’m not doing things the right way but since
it is working on windows and used to work until now with my Mac …
Thanks in advance for your help (below the simple test and the error obtained)
Regards
Robin
#include <Rcpp.h>
using namespace Rcpp;
class MyModel
{
public:
double a;
~MyModel();
MyModel();
MyModel(const Rcpp::NumericVector& ModelData, int temp);
};
RCPP_EXPOSED_CLASS(MyModel)
MyModel::~MyModel()
{}
MyModel::MyModel() : a(0)
{}
MyModel::MyModel(const Rcpp::NumericVector& ModelData, int temp) : a(0)
{}
RCPP_MODULE(MyModel){
Rcpp::class_<MyModel>("MyModel")
.constructor()
.constructor<const Rcpp::NumericVector &, int>()
;
}
