[R] How to generating diagnal blocks ?

2006-09-21 Thread Tong Wang 
Hi,
 I am trying to creat a matrix with diagnal blocks, say, I have a matrix X 
of any dimension (nxm) ,and would like to have:
   
X
X
X
  .
otherwise space filled with 0's.   Is there a handy way to do this ?

Thanks a lot in advance.

If I remember well, there should be a package including the function 
bdiag() making the job..but I am not able to remember its name..

However a quick search via RSiteSearch(bdiag) yields

Hope this helps you,

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,]135000
[2,]246000
[3,]000147
[4,]000258
[5,]000369
 


the function also has extra functionality over the one Vito
points to in the archives.
