Joseph K. Bradley commented on SPARK-11558:
-------------------------------------------
We'll need to make it specific to LinearRegressionModel and
LogisticRegressionModel for now since those are the only models which store
enough info about the input data. Later, we could make it part of more Models
which inherit from HasFeatures.

> SparkRWrappers.getModelFeatures is a really useful method but only available
> in R. We should provide its functionality as a helper method in all
> languages (but perhaps with a different API to make it accessible from more
> than a printed summary).
