Public methodStatic memberCreateU, T, TAccumulator(Boolean)
Constructs a new aggregator that uses the specified accumulator.
Public methodStatic memberCreate2U, T, TAccumulator
Constructs a new aggregator that uses the specified accumulator.
Public methodStatic memberQuantile(Double)
Gets an aggregator that computes the specified quantile.
Public methodStatic memberQuantile(Double, Int32)
Gets an aggregator that computes the specified quantile.

Fields

  NameDescription
Public fieldStatic memberOpenHighLowClose
Defines a set of aggregators that return the OHLC (Open, High, Low, Close) prices.

Remarks

Use the Aggregators class to access many common aggregation functions. Most aggregators are returned as Aggregator2Group objects, which means they can be used on untyped data frame columns.
