Hello
You need adiag(), which
is now part of the magic package:
> library(magic)
> adiag(matrix(1:6,2,3),matrix(1:9,3,3))
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] 1 3 5 0 0 0
[2,] 2 4 6 0 0 0
[3,] 0 0 0 1 4 7
[4,] 0 0 0 2 5 8
[5,] 0 0 0 3 6 9
>
the function also has extra functionality over the one Vito
points to in the archives.
