Aggregate<T, U>(Func<Vector<T>, U>)

Applies the specified aggregators to all the columns in the data frame.
C# 
public Vector<U> Aggregate<T, U>(
	Func<Vector<T>, U> aggregator
)

Parameters

aggregator  Func<Vector<T>, U>
One or more aggregators to use.

Type Parameters

T
The element type of the input to the aggregation.
U
The type of the result of the aggregation.

Return Value

Vector<U>
A new data frame that contains the result of the aggregations with rows indexed by the names of the aggregators and columns indexed by the data frame's column index.

Aggregate<T, U, V>(Func<Vector<T>, V>, Func<Vector<U>, V>)

Applies the specified aggregators to all the columns in the data frame.
C# 
public DataFrame<string, C> Aggregate<T, U, V>(
	Func<Vector<T>, V> aggregator1,
