new-column clj

(new-column name data)

(new-column name data metadata)

(new-column name data metadata missing)

Given a map of (something convertible to a long reader) missing indexes, (something convertible to a reader) data and a (string or keyword) name, return an implementation of enough of the column and datatype protocols to allow efficient columnwise operations of the rest of tech.ml.dataset
