Parameters
- dataFrames
- Type: System.Collections.GenericIEnumerableDataFrameR, C
A sequence of data frames. - 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 .
Type Parameters
- R
- The element type of the row index of the data frames.
- C
- The element type of the column index of the data frames.
Return Value
Type:
DataFrameR,
CA new data frame that consists of the rows of all data frames in
dataFrames appended in order,
retaining only those columns that are
in
newColumnIndex.
If two columns have the same column key, but different element types,
both columns are retained.
