[Rcpp-devel] Multidimensional List (List of Lists)

a) You posted twice. That's close to spamming.

b) Your example is incomplete and non-reproducible. Not a way to earn brownie
points either.

#include <Rcpp.h>

using namespace Rcpp;

// [[Rcpp::export]]
List reclist(){
     List a(2);
     List output(2);
     output[0] = IntegerVector::create( 10, 20 ) ;
     output[1] = IntegerVector::create(_["foo"] = 20,
				      _["bar"] = 30 ) ;
     a[0] = output;
     a[1] = output;
     return a;
}
