Frame | List[Frame] | None

force

bool

return

Frame

• rbind() – function for row-binding several frames.

• dt.Frame.cbind() – Frame method for cbinding some frames to another.

Examples

from datatable import dt, f DT = dt.Frame(A=[1, 2, 3], B=[4, 7, 0]) DT

	A	B
	int32	int32
0	1	4
1	2	7
2	3	0

3 rows × 2 columns

frame1 = dt.Frame(N=[-1, -2, -5]) frame1

	N
	int32
0	-1
1	-2
2	-5

3 rows × 1 column

dt.cbind([DT, frame1])

	A	B	N
	int32	int32	int32
0	1	4	-1
1	2	7	-2
2	3	0	-5

3 rows × 3 columns

If the number of rows are not equal, you can force the binding by setting the force parameter to True:

frame2 = dt.Frame(N=[-1, -2, -5, -20]) frame2

	N
	int32
0	-1
1	-2
2	-5
3	-20

4 rows × 1 column

dt.cbind([DT, frame2], force=True)

	A	B	N
	int32	int32	int32
0	1	4	-1
1	2	7	-2
2	3	0	-5
3	NA	NA	-20

4 rows × 3 columns
