[R] creating cubes

What is the best way to store data in a cube? That is, I need to create a
data structure D with three indexes, say i,j,h, so that I can access each
data point D[i,j,h], and visualise sections like D[i,j,] or D[,,h].
I have tried to create an array of matrixes:
but then D[i] returns a number, and not a matrix.
I imagine this is a dummy question, but I did search for an answer on
various R help sites, and found nothing straightforward. Being an
inexperienced R user, I prefer a simple solution, even at some efficiency
Many thanks for your help.
