m <- matrix( rep( y, length( x ) ), length( y ), length( x ) )

Hi guys

I have vectors x <- c(1,2,3,4) and y <- c(4,3,9) and would like to generate a matrix which has 3 rows (length(y)) and 4 

columns (length(x)), and each row is the corresponding y element repeated length(x) times.

4,4,4,4
3,3,3,3
9,9,9,9

Thanks.

Fernando ?lvarez
