collect is shown in the example section instead of map

This is fully the case for the 2.0 doc (http://ruby-doc.org/core-2.0/Enumerable.html#method-i-map) and partially the case for the 2.1 doc (http://ruby-doc.org/core-2.1.0/Enumerable.html#method-i-map).

For example, from http://ruby-doc.org/core-2.1.0/Enumerable.html#method-i-map:

(1..4).map { |i| i*i }      #=> [1, 4, 9, 16]
(1..4).collect { "cat"  }   #=> ["cat", "cat", "cat", "cat"]

(1..4).collect { "cat"  }   #=> ["cat", "cat", "cat", "cat"]

That's intentional, both methods are aliases (note that the documentation for #collect and #map is the same).
