[Rcpp-devel] Is there an Rcpp class for arrays with > 2 dimensions?

I may be confusing Armadillo classes and Rcpp classes but I seem to
recall that there is an Rcpp class for arrays with more than 2
dimensions.  However, I can't find anything that looks like that in
the declarations or in the unit tests.  I can easily create such an
object by installing a dim attribute on a Vector type but I didn't
want to reinvent the wheel.

Is there such a class or am I misremembering?
