HI, I have installed Cursive on my IntelliJ Community Version. You have two options to reformat the code. One in the menu Code->"Reformat Code" or CTRL + ALT + L. This should reformat your code. Best regards Marcus Am Sa., 19. Dez. 2020 um 15:48 Uhr schrieb waleed sheikh : > Any one have idea

Re: clojure, not the go to for data science

I wonder, has somebody ever tried to write something like a clojure wrapper for WEKA (http://www.cs.waikato.ac.nz/ml/weka/) or added WEKA to a clojure project? I have done this for a classification problem, but it was rather inchoate and only to create some libsvm and naive bayes classifier.

Re: clojure.set/union bug?

As it seems clojure.set/union can be used with maps as parameters too. =>(clojure.set/union {:a 1 :b 2 :c 3 :d 4} {:a 1 :b 4 :c 4}) {:a 1, :c 4, :b 4, :d 4} So it is possible to get a union of keys of a map with => (keys (clojure.set/union {:a 1 :b 2 :c 3 :d 4} {:a 1 :b 4 :c 4})) (:a :c :b :d) I
