Sorry about that, didn't see that :b should concat it's vals: (def x [[:a 1] [:b 3] [:b 5] [:c 1]]) (reduce (fn [x [k v]] (assoc x k (if (contains? x k) (conj (x k) v) [v]))) {} x)
Returns: {:c [1], :b [3 5], :a [1]} -- Krešimir Šojat --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
