Incorrect parameter for ds/random-split

[chamaeleon]

mushrooms.clj has the code

(let [[mushroom-train mushroom-test] (ds/random-split dataset [70 30])
  ...)

However, ds/random-split is currently defined as

(defn random-split
  [dataset & ratios]
  (.randomSplit dataset (int-array ratios)))

which means ratios becomes a list containing one element, the array [70 30], instead of a list containing 70 and 30. Either the mushrooms.clj code need to be updated to be

(let [[mushroom-train mushroom-test] (ds/random-split dataset 70 30)
  ...)

or the ampersand needs to be removed from the random-split definition.

I would assume the former (changing the call in mushrooms.clj) is preferable since it is an example, and not an API function that may be in use by other people.

Yes, I was thinking using vector is more clojure-style, but at last plain number list style is decided.
