mymapの作成と同時に、「mymap」の値を文字列のリストではなくDoubleのリストに変換するにはどうすればよいですか?
(use '[clojure.string :only (join split)])
;(def raw-data (slurp "http://ichart.finance.yahoo.com/table.csv?s=INTC"))
;Downloaded and removed the first line
(def raw-data (slurp "table-INTC.csv"))
(def raw-vector-list
(map
#(split % #",") ; anonymous map function to split by comma
(split raw-data #"\n"))) ; split raw data by new line
(pr (take 1 raw-vector-list))
(def mymap
(zipmap
;construct composite key out of symbol and date which is head of the list
(map #(str "INTC-" %) (map first raw-vector-list))
;How do i convert these values to Double instead of Strings?
(map rest raw-vector-list)))
(pr (take 1 mymap))
