You can then do a first plot with your first set of points, then call par(new=T), and plot your second set of points whilst setting the axis type to "none", so the axes are not ploted. Then you can use 'axis' to display a new axis in teh position you want for the new range of points... repeat if needed for other sets. I hope this sets you in the right direction.
