I don't think you can use matrix() to store other matrix() inside.
But array() is a solution to store matrix() inside.
(At least I have use it).
You _can_ do this with matrix() (although that was not quite what was
asked). Try
a <- b <- c <- d <- matrix(1:4, 2, 2)
e <- matrix(list(a,b,c,d), 2,2)
e
e[1,2][[1]]
