| Hi, I am trying to send a 3 dimensional object from C++ to R as an R array. I don’t know how to construct an R array in C++ using Rcpp.  I am hoping to look at an example from one of the CRAN packages that use Rcpp.  Can anyone recommend a package that I should look into?

The unit test files are a first stop -- look at both


This can be as simple as

// [[Rcpp::export]]
IntegerVector integer_dimension_ctor_3(){
    return IntegerVector( Dimension( 2, 3, 4) ) ;
