What do you mean ?
I looked at my code again and what I actually tried to do was:
#include <Rcpp.h>
RcppExport SEXP multidim() {
BEGIN_RCPP
Rcpp::NumericMatrix nv(Rcpp::Dimension(2,3,4));
return nv;
END_RCPP
}
So I incorrectly used NumericMatrix instead of NumericVector, and this
will not compile. Switching to NumericVector works.
So I guess what you are saying is that the multi-dimensional "matrix"
support present but not yet complete.
Thanks,
Dominick
That makes sense, in R a matrix is of dimension 2, not 1, not 3, just 2.
What Doug was looking for is an Rcpp class representing an R __array__,
which have any number of dimensions.
There is currently no Rcpp::Array class, this is not complicated code to
write, we just need to find someone with enough motivation.
Tomorrow is another day, so maybe tomorrow me will do it.
