This now works with Row and Col too, as in :
test.armadillo.sugar.ctor <- function(){
fx <- cxxfunction( signature(x= "numeric") , '
NumericVector xx(x) ;
arma::mat m = xx + xx ;
arma::colvec co = xx ;
arma::rowvec ro = xx ;
return List::create(
After some discussion this morning with Conrad (who develops Armadillo),
we've come up with a way that is not too intrusive on armadillo itself
(it adds about 6 lines of code), yet opens a door for RcppArmadillo to
adds its own constructors to the Mat template class.
I've added this one now :

Hello,
After the last thread, I looked again at armadillo and came up with a
way to make it aware of Rcpp sugar, so that we can create an armadillo
matrix from an Rcpp sugar expression, without having to assign the
expression into an Rcpp vector.
For example :
NumericVector xx(x) ;
