As Dirk suggested below, I'm working on a paragraph to point out the
constructor used implies no modification of the arma::mat memory.

Since you changed the function name, you can no longer call rcpp_hello_world()
from R. Try calling the new function name.
Better yet, start over, leave rcpp_hello_world code alone and add another .cpp,
.h, and .R file with another function.

I haven't been very active lately with Rcpp, but I like Nathan's advice below.
Don't redefine assert(), I think that's not friendly to inexperienced people
and will just generate more questions.

This also offers a viable way to test this type of code for those who don't
have MATLAB.

Hi,
Instead of posting this code to the list, a better idea is to write up your
solution for RcppGallery. That way you can share code with a wider audience.

Wrap the Rcpp headers in an #if/#endif. That way, when you our outside of R,
the Rcpp code is skipped.
I used this idea in 2013-2014 to build in R using Rcpp, and the same code in
Visual Studio.

I’m available for volunteer efforts to a limited extent.
