core.matrix datasets have 3 attributes than can be accessed by treating the dataset as a map.

Let's take this example dataset:

(def dataset-test
    (clojure.core.matrix.dataset/dataset [{:a 1 :b 11}
                                          {:a 2 :b 12}
                                          {:a 3 :b 13}]))

Multimethods

-> an implementation of polymorphism in Clojure

What Clojure doc says:

A Clojure multimethod is a combination of a dispatching function, and one or more methods. When a multimethod is defined, using defmulti, a dispatching function must be supplied. This function will be applied to the arguments to the multimethod in order to produce a dispatching value.

;; comp vs juxt
;; they both take in function(s) as arguments and associate then in a way

;; juxt (http://clojuredocs.org/clojure.core/juxt) returns a function that is a juxtaposition of other functions:

(map #((juxt name str/capitalize) %) [:name :location :unit]) ;;=> (["name" ":name"] ["location" ":location"] ["unit" ":unit"])

;; Let's have a pick at the source code:
(defn juxt 
  "Takes a set of functions and returns a fn that is the juxtaposition
