Parameters
- frame
- Type: Extreme.DataAnalysisDataFrameTupleR1, 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:
DataFrameTupleR1,
R2,
C,
Int64A 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
DataFrameTupleR1,
R2,
C. When you use instance method syntax to call this method, omit the first parameter. For more information, see
