Parameters

dataFrames

Type: System.Collections.GenericIEnumerableDataFrameR, C
A sequence of data frames.

columnJoinType (Optional)

Type: Extreme.DataAnalysisJoinType
Specifies how columns that do not appear in all data frames should be handled.

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

Only Inner or Outer are supported for the columnJoinType argument. Left and right joins of two data frames can be obtained using an overload of this method which lets you specify the columns to be retained as an index.

If two columns have the same column key, but different element types, both columns are retained.
