[R] How to draw arrows or segment lines in 3 dimensional graph

[yabado]

Hi

I have a dataset which is like this:
ID	X1	Y1	Z1	X2	Y2	Z2
1	32	127	85	31.7	121	85
2	37.9	153	88	34.6	137	90
3	36.8	134	88	36.1	155	97
4	31.4	136	87	29	113	70


I would like draw the arrow or segment line for each ID from (x1, y1, z1) to
(x2, y2, z2)
Is there a way to do this kind of 3-D graph.

Thank you
