Subject: [Nuby] Sorting a Hash and keepint it as a Hash?

Another nuby question:

I have a Hash of objects which I want to sort by the values. Afterwards
I want to pull out the keys as one array and the values as another. So I
have code like so:

# sort by frequency ascending
@fault_sums =3D @fault_sums.sort {|a,b| a[1] <=3D> b[1]}
# Only keep top N
@fault_sums.slice!(0...-@number) if @number <=3D @fault_sums.size=20
   =20
fields =3D @fault_sums.keys
data =3D @fault_sums.values

But when I get to calling keys and values on the Hash I realized, sort
actually returns back a 2D array and those methods aren't defined on an
Array. Is there a way to make the 2D Array returned by the sort back
into a Hash?

Thanks,
Chris Williams
