[Rcpp-devel] Copy rownames and colnames from a NumericMatrix to another NumericMatrix

[Florian Plaza Oñate]

Hi everyone,

I am trying to copy the rownames and the colnames from a NumericMatrix 
to another NumericMatrix by using Rcpp

Here is my code:

Rcpp::NumericMatrix copy(const Rcpp::NumericMatrix& m)
{
  Rcpp::NumericMatrix m2(num_genes, num_samples);
  Rcpp::rownames(m2) = Rcpp::rownames(m);
  Rcpp::colnames(m2) = Rcpp::colnames(m);

  return m2;
}

It does change the default rownames and colnames of the NumericMatrix.
Do you know how to do it?

Thanks in advance.
