If you install the facets gem you can use "frequency"

e.g.

>irb
irb:> require 'rubygems'
=> false
irb:> require 'facets'
=> true
irb:> x = %w[a b d e e rkeke ele e ee e e el d]
=> ["a", "b", "d", "e", "e", "rkeke", "ele", "e", "ee", "e", "e", "el",
"d"]
irb:> x.frequency
=> {"ee"=>1, "a"=>1, "b"=>1, "d"=>2, "e"=>5, "el"=>1, "ele"=>1,
"rkeke"=>1}
