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

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

Parameters

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

Type Parameters

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

Return Value

Vector<TResult>
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<T1, T2, TResult>(Func<Vector<T1>, TResult>, Func<Vector<T2>, TResult>)

Applies the specified aggregators to all the columns in the data frame.
C# 
public DataFrame<string, C> Aggregate<T1, T2, TResult>(
	Func<Vector<T1>, TResult> aggregator1,

TResult
The type of the result of the aggregation.

Return Value

DataFrame<String, C>
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<T1, T2, T3, TResult>(Func<Vector<T1>, TResult>, Func<Vector<T2>, TResult>, Func<Vector<T3>, TResult>)
