Eh. (map #(/ votes %) (iterate inc 1)) itself produces a lazy sequence, since map and iterate are lazy. > I don't know how to filter and work with the vector & map in order to > apply that function for each party, in each province. > I have been trying to use the filter function but I get the following > error: > > user=> (filter #"A" [["A" "p1" "32"] ["B" "p1" "55"] ["A" "p2" "77"] > ["B" "p2" "21"]]) > java.lang.ClassCastException: java.util.regex.Pattern cannot be cast > to clojure.lang.IFn For this, you can just use #(= "A" %) as your predicate; there's no need to use regex matching. If you need a regex, use #(re-matches #"pattern" %) as your predicate, instead of the regex itself. > Thanks again and I will be posting any advances!
