A Frame is a finite Int-indexed collection of rows.

Documentation

data Frame r

A Frame is a finite collection of rows indexed by Int.

Constructors

Frame

Fields

• frameLength :: !Int
• frameRow :: Int -> r

Instances

Monad Frame

Methods

(>>=) :: Frame a -> (a -> Frame b) -> Frame b

(>>) :: Frame a -> Frame b -> Frame b

return :: a -> Frame a

fail :: String -> Frame a

Functor Frame

Methods

fmap :: (a -> b) -> Frame a -> Frame b

(<$) :: a -> Frame b -> Frame a

Applicative Frame

Methods

pure :: a -> Frame a

(<*>) :: Frame (a -> b) -> Frame a -> Frame b

(*>) :: Frame a -> Frame b -> Frame b

(<*) :: Frame a -> Frame b -> Frame a

Foldable Frame

Methods

fold :: Monoid m => Frame m -> m

foldMap :: Monoid m => (a -> m) -> Frame a -> m

foldr :: (a -> b -> b) -> b -> Frame a -> b

foldr' :: (a -> b -> b) -> b -> Frame a -> b

foldl :: (b -> a -> b) -> b -> Frame a -> b

foldl' :: (b -> a -> b) -> b -> Frame a -> b

foldr1 :: (a -> a -> a) -> Frame a -> a

foldl1 :: (a -> a -> a) -> Frame a -> a

toList :: Frame a -> [a]

null :: Frame a -> Bool

length :: Frame a -> Int

elem :: Eq a => a -> Frame a -> Bool

maximum :: Ord a => Frame a -> a

minimum :: Ord a => Frame a -> a

sum :: Num a => Frame a -> a

product :: Num a => Frame a -> a

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.

Methods

mempty :: Frame r

mappend :: Frame r -> Frame r -> Frame r

mconcat :: [Frame r] -> Frame r

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.
