SeriesK, VResampleTNewKey, R Method (IEnumerableK, Direction, FuncTNewKey, SeriesK, V, R, FuncK, SeriesK, V, TNewKey)
Resample the series based on a provided collection of keys. The values of the series are aggregated into chunks based on the specified keys. Depending on `direction`, the specified key is either used as the smallest or as the greatest key of the chunk (with the exception of boundaries that are added to the first/last chunk). Such chunks are then aggregated using the provided `valueSelector` and `keySelector` (an overload that does not take `keySelector` just selects the explicitly provided key). ## Parameters - `keys` - A collection of keys to be used for resampling of the series - `direction` - If this parameter is `Direction.Forward`, then each key is used as the smallest key in a chunk; for `Direction.Backward`, the keys are used as the greatest keys in a chunk. - `valueSelector` - A function that is used to collapse a generated chunk into a single value. Note that this function may be called with empty series. - `keySelector` - A function that is used to generate a new key for each chunk. ## Remarks This operation is only supported on ordered series. The method throws `InvalidOperationException` when the series is not ordered. [category:Resampling]
