Functor Frame

Applicative Frame

Foldable Frame

Monoid (Frame r)

The Monoid instance for Frame provides a mechanism for vertical concatenation of Frames. That is, f1 <> f2 will return a new Frame with the rows of f1 followed by the rows of f2.

type FrameRec rs = Frame (Record rs)

A Frame whose rows are Record values.

boxedFrame :: Foldable f => f r -> Frame r

Build a Frame from any Foldable. This simply uses a boxed Vector to hold each row. If you have a collection of Records, consider using toFrame.

zipFrames :: FrameRec rs -> FrameRec rs' -> FrameRec (rs ++ rs')

Horizontal Frame concatenation. That is, zipFrames f1 f2 will return a Frame with as many rows as the smaller of f1 and f2 whose rows are the result of appending the columns of f2 to those of f1.
