[R] replicate matrix

[wendy]

Hi all,

I have a matrix, for example
     [,1] [,2]
[1,]  1    3
[2,]  4    6

I want to replicate the matrix twice and add an extra column at the end,
which is
     [,1] [,2] [,3] [,4] [,5] [,6] [,7]
[1,]  1    3     1    3     1    3    2
[2,]  4    6     4    6     4    6    5

I found 'rep' only works for vector. Does anyone know how to replicate a
matrix, and append the matrix?

Thank you in advance,
Wendy
