SeriesK, VAggregateTNewKey, R Method (AggregationK, FuncDataSegmentSeriesK, V, TNewKey, FuncDataSegmentSeriesK, V, OptionalValueR)
Aggregates an ordered series using the method specified by `Aggregation<K>` and then applies the provided `valueSelector` on each window or chunk to produce the result which is returned as a new series. A key for each window or chunk is selected using the specified `keySelector`. ## Parameters - `aggregation` - Specifies the aggregation method using `Aggregation<K>`. This is a discriminated union listing various chunking and windowing conditions. - `keySelector` - A function that is called on each chunk to obtain a key. - `valueSelector` - A value selector function that is called to aggregate each chunk or window.
