	recurrence As Recurrence,
	aggregators As IDictionary(Of C, AggregatorGroup),
	Optional direction As Direction = Direction.Backward

	DataFrame<DateTime, C>^ frame, 
	Recurrence^ recurrence, 
	IDictionary<C, AggregatorGroup^>^ aggregators,

static member Resample : 
        frame : DataFrame<DateTime, 'C> * 
        recurrence : Recurrence * 
        aggregators : IDictionary<'C, AggregatorGroup> * 
        ?direction : Direction 
(* Defaults:
        let _direction = defaultArg direction Direction.Backward
*)
-> DataFrame<DateTime, 'C>

Parameters

frame DataFrame<DateTime, C>: A data frame.
recurrence Recurrence: The recurrence pattern to resample to.
aggregators IDictionary<C, AggregatorGroup>: A dictionary that maps column keys to aggregators.
direction Direction (Optional): Indicates whether the entries in frame's row index should be taken as the start (Forward) or end (Backward) of a sampling interval.

Type Parameters

C

Return Value

DataFrame<DateTime, C>
A new data frame with a column for each entry in aggregators which is the result of resampling the column with the entry's key using the specified recurrence pattern and the aggregator in the entry's value. The order of the columns is preserved.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type DataFrame<DateTime, C>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

A new data frame which is the result of resampling each column with the corresponding aggregator in aggregators.

Usage Note

Exceptions

ArgumentNullException

frame is null.

-or-

recurrence is null.

-or-
