Yes. Nobody wrote such a converter. Maybe you and your student want to take a stab? | I can build this cube from an input vector using explicit nested loops.

Array plus dim attribute may work. I used arma::cube quite extensively in one project, but only at the C++ level as a container. Results back to R were always of lesser dimension.
