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