Dear Rcpp-Devels,
I am a little confused right now with the following setting:
I have a C++ class with for example the following header
#include <RcppArmadillo.h>
class FirstClass {
public:
Rcpp::NumericMatrix M;
FirstClass(Rcpp::S4& classS4);
~FirstClass();
}
Then, in the .cc file I have:
#include <RcppArmadillo.h>
#include "FirstClass.h"
FirstClass::FirstClass(Rcpp::S4& classS4) {
M(classS4.slot("M_R")); // array M_R in R
};
FirstClass::~FirstClass(){};
Now, my compiler always gives me an error:
error: no match for call to ‘(Rcpp::NumericMatrix {aka Rcpp::Matrix<14>})
(Rcpp::RObject::SlotProxy)’
Do I have to create the Matrix in the constructor differently? I want to reuse
memory allocated in R. Further, could the error be triggered by M_R being an
array in R?
Best
Simon
