This is so awesome. Thanks for writing this!
Here's my naive stab at integration with (the :iris dataset available in)
Incanter...
(:require [incanter.core :as i]
[incanter.datasets :as id]
[com.stuartsierra.frequencies :as freq])
(def d (id/get-dataset :iris))
(for [k [:Sepal.Length :Sepal.Width :Petal.Length :Petal.Width ]
]
(-> d
i/to-map
k
frequencies
freq/stats
(assoc :field k) ;; label the stats with the field we
used
))
What do people think about Incanter these days? Is it a forgotten
step-child of clojure data science dreams or ready for a renaissance?
Cheers,
Avram
