@otfrom there's no reason that reducers couldn't be made to work as arguments to c.c.m.dataset API functions. And then you could use transducers as usual. If there's a use case, happy to consider.

The idea of clojure.core.matrix.dataset is similar to the main clojure.core.matrix API: we provide a set of useful and general purpose API functions that can be supported by multiple implementations (e.g. you can have data tables from spark, JDBC result sets, Clojure data structures etc.)

@mikera I'd never thought of using transducers on a c.c.m.dataset w/out changing it to a row-seq first. I'll have a look at the API again and see if I can figure out how to get a reducer in there (cc @elise_huard)
