Extreme Optimization Numerical Libraries for .NET Professional
Transforms a data frame so that the column index is nested into the row index.

Namespace:  Extreme.DataAnalysis
Assembly:  Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.1
Syntax

VB
C++
F#
Copy
public static DataFrame<(R1 , R2 , C ), long> Stack<R1, R2, C>(
	this DataFrame<(R1 , R2 ), C> frame,
	bool excludeMissing = true
)
<ExtensionAttribute>
Public Shared Function Stack(Of R1, R2, C) ( 
	frame As DataFrame(Of ( As R1,  As R2), C),
	Optional excludeMissing As Boolean = true
) As DataFrame(Of ( As R1,  As R2,  As C), Long)
public:

[<ExtensionAttribute>]
static member Stack : 
        frame : DataFrame<ValueTuple<'R1, 'R2>, 'C> * 
        ?excludeMissing : bool 
(* Defaults:
        let _excludeMissing = defaultArg excludeMissing true
*)
-> DataFrame<ValueTuple<'R1, 'R2, 'C>, int64> 

Parameters

frame
Type: Extreme.DataAnalysisDataFrameValueTupleR1, R2, C
A data frame.
excludeMissing (Optional)
Type: SystemBoolean
Indicates whether a row should be omitted if the value is missing. The default is .

Type Parameters

R1
The element type of the first level of the row index of the data frame.
R2
The element type of the second level of the row index of the data frame.
C
The element type of the column index of the data frame.

Return Value

Type: DataFrameValueTupleR1, R2, C, Int64
A new data frame whose row index is a hierarchical index where the first level corresponds to the row index of frame, and the second level corresponds to the column index of frame.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type DataFrameValueTupleR1, R2, C. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
