DataFrameR, CAppend Method (DataFrameR, C, IndexC, Boolean)

Extreme Optimization Numerical Libraries for .NET Professional
Combines two data frames by appending the rows of the right data frame to the rows of this data frame.

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

C#
VB
C++
F#
Copy
public DataFrame<R, C> Append(
	DataFrame<R, C> right,
	Index<C> newColumnIndex,
	bool verify = true
)
Public Function Append ( 
	right As DataFrame(Of R, C),
	newColumnIndex As Index(Of C),
	Optional verify As Boolean = true
) As DataFrame(Of R, C)
public:
DataFrame<R, C>^ Append(
	DataFrame<R, C>^ right, 
	Index<C>^ newColumnIndex, 
	bool verify = true
)

        right : DataFrame<'R, 'C> * 
        newColumnIndex : Index<'C> * 
        ?verify : bool 
(* Defaults:
        let _verify = defaultArg verify true
*)
-> DataFrame<'R, 'C> 

Parameters

right
Type: Extreme.DataAnalysisDataFrameR, C
A data frame with the same index.
newColumnIndex
Type: Extreme.DataAnalysisIndexC
An index that specifies the columns that should be retained in the combined data frame.
verify (Optional)
Type: SystemBoolean
Optional. Indicates whether uniqueness of the values in the combined index should be verified. The default is .

Return Value

Type: DataFrameR, C
A new data frame that consists of the rows of the current data frame followed by the rows of right.
Exceptions
