[R] repeating rows or columns within a matrix

[Juhana Vartiainen]

Hello

Spse I have a matrix, say

1 2 3
4 5 6
7 8 9

and I would like to expand it by repeating rows within the matrix, to
get, if the repeating factor is 2, say:

123
123
456
456
789
789

(or columnwise as well) . There must be a smart way of doing that?

Many thanks
