Hi,
I can use the following code to generate a matrix, each column of
which is 'x'. But I have to specify '5' twice in the second command. I
am wondering if there is a better way to do it.
x=1:10
matrix(rep(x,5),nc=5)
t(matrix(rep(x,5),nc=5))
Regards,
Peng
This works for me:
> do.call( cbind, rep( list( x ), 5 ) )
> do.call( rbind, rep( list( x ), 5 ) )
