Dear R users,
I have a question about matrix manipulation with its rows.
Plz see the simple example below
sample <- list(matrix(1:6, nr=2,nc=3), matrix(7:12, nr=2,nc=3),
matrix(13:18,nr=2,nc=3))
> sample
[[1]]
[,1] [,2] [,3]
[1,] 1 3 5
[2,] 2 4 6
[[2]]
[,1] [,2] [,3]
[1,] 7 9 11
[2,] 8 10 12
[[3]]
[,1] [,2] [,3]
[1,] 13 15 17
[2,] 14 16 18
With this list, I'd like to create this below
[[1]]
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 1 3 5 0 0 0
[2,] 0 0 0 2 4 6
[[2]]
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 7 9 11 0 0 0
[2,] 0 0 0 8 10 12
[[3]]
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 13 15 17 0 0 0
[2,] 0 0 0 14 16 18
Any suggestion will be greatly appreciated.
Regards,
Kathryn Lord
