1...........Kindly tell me is it possible to form a matrix which contains a no of matrices.. for eg.. if a,b,c,d are matrices.... and e is a matrix which contains a,b,c,d as rows and columns..
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]]
