divide an array to create multidimensional array

Question

I'm looking for a method to divide a one dimensional array by a number n to create a multidimensional array with each element having (at most) length n. For example

[1,2,3,4,5,6] / 3

should result in:

[[1,2,3],[4,5,6]]

This should do it...

chunkedArr = arr.each_slice(3).to_a;

@pguardiario I couldn't get it to work in CodePad.org and I'm not a Ruby guru, is it working for you?

More fun: class Array; def /(n); each_slice(n).to_a; end; end :)
