[R] split a y-axis to show data on different scales

I think information can be enhanced by using different scaled graphs next to
each other. mfrow() created too much space, there may be no need to again draw
the x-axis. It can be very useful to have different scales of the same data
presented next to each other, in addition to the main graph. So I think the data
of the person who started this thread could be displayed using one graph will
all the data, and then a superimposed graph (sharing same x-axis) on any part of
the data to give an enhanced visual communication. Drawing grid lines with same
tick marks in both graphs can enhance this visual communication. This is like
"static zooming". Of course it is important to make sure that the change in
scale is evident, because it is needed for the interpretation of the
graph---using a grid with same tick marks can produce this effect visually.
