Subject: [R] Please help! Matrices and parameter of time

Hi, Well, the solution to my problem maybe is easy, but i have
really stuck with this.
I have a process which evolves in three times, so there is the
parameter of time (t=1,2,3).More particularly i have three 4*4
matrices, one for each time. In other words each element has
three cordinates: time, row and column.
The problems are these:i don't know how to express these
matrices.Also i don't know how can i extract each element, for
example, if i want the element from the matrix corresponding to
the 3d time, the  2nd row, the 3d column, how will i extract
I would appreciate any help and idea!Thank you!Anna S.
