If I have two matrices like

x <- matrix(rep(c(1,2,3),3),3)
y <- matrix(rep(c(4,5,6),3),3)

How can I combine  them to get ?

1 1 1 4 4 4
1 1 1 5 5 5
1 1 1 6 6 6
2 2 2 4 4 4
2 2 2 5 5 5
2 2 2 6 6 6
3 3 3 4 4 4
3 3 3 5 5 5
3 3 3 6 6 6

The number of rows and the actual numbers above are unimportant, they are given so as to illustrate how I want to combine the matrices.  I.e., I am looking for a general way to combine the first row of x with each row of y, then the second row of x with y, ....

Thanks,

Dan
