rows are grouped in the dataframe. This can only be used with
aggregate.

toMarkdownTable :: DataFrame -> Text Source #
For showing the dataframe as markdown in notebooks.
toMatrix :: DataFrame -> Either DataFrameException (Vector (Vector Float)) Source #
Returns a dataframe as a two dimentions vector of floats.
All entries in the dataframe must be doubles. This is useful for handing data over into ML systems.
columnAsVector :: Columnable a => Text -> DataFrame -> Vector a Source #
Get a specific column as a vector.
You must specify the type via type applications.
