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
