FrameTRowKey, TColumnKeyZipV1, V2, V3 Method (FrameTRowKey, TColumnKey, JoinKind, JoinKind, Lookup, FuncV1, V2, V3)
Aligns two data frames using both column index and row index and apply the specified operation on values of a specified type that are available in both data frames. The parameters `columnKind`, and `rowKind` can be specified to determine how the alginment works (similarly to `Join`). Column keys are always matched using `Lookup.Exact`, but `lookup` determines lookup for rows. Once aligned, the call `df1.Zip<T>(df2, f)` applies the specifed function `f` on all `T` values that are available in corresponding locations in both frames. For values of other types, the value from `df1` is returned. ## Parameters - `otherFrame` - Other frame to be aligned and zipped with the current instance - `columnKind` - Specifies how to align columns (inner, outer, left or right join) - `rowKind` - Specifies how to align rows (inner, outer, left or right join) - `lookup` - Specifies how to find matching value for a row (when using left or right join on rows) Supported values are `Lookup.Exact`, `Lookup.ExactOrSmaller` and `Lookup.ExactOrGreater`. - `op` - A function that is applied to aligned values. The `Zip` operation is generic in the type of this function and the type of function is used to determine which values in the frames are zipped and which are left unchanged.
