[R] Matrixes inside matrixes

[baptiste auguie]

Hi,

You can have each cell of a matrix contain a matrix, but for a reason
that is just not clear to me the matrices are wrapped in a list,

m = matrix(replicate(4,matrix(1:9,3,3),simplify=FALSE), 2,2)

m[1,2][[1]]

str(m)

and even more surprising to me, m itself has become a list for some reason.
