Hi,
I have an array and I want to put in into a matrix x number of times. Currently
I doing this
matrix <- cbind(array, array, array).
Is there a more elegant way of doing this?
Fortunately!
If 'array' really is a matrix (bad choice of names here, Bub!), then
a.matrix <- matrix( rep( array, 3 ), nc = ncol( array )* 3 )
But this will work too:
a.matrix <- do.call( cbind, rep( list( array ), 3) )
even if 'array' is a data.frame
HTH,
Chuck
I've tried
matrix <- cbind(rep(array, times=x)) and matrix <- rep(cbind(array), times = 5)
but it didn't work.
Thanks.
