static member GetRows : 
        frame : DataFrame<ValueTuple<'R1, 'R2, 'R3>, 'C> * 
        key : 'R1 -> DataFrame<ValueTuple<'R2, 'R3>, 'C> 

Parameters

frame
Type: Extreme.DataAnalysisDataFrameValueTupleR1, R2, R3, C
A data frame.
key
Type: R1
A key in the first level of the index.

Type Parameters

R1
The type of the first level of the index.
R2
The type of the second level of the index.
R3
The type of the third level of the index.
C
The element type of the column index.

Return Value

Type: DataFrameValueTupleR2, R3, C
A data frame with a two-level hierarchical row indexes with levels of type R2 and R3 that contains the rows of frame whose key has the value key at the first level.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type DataFrameValueTupleR1, R2, R3, 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).
