Hi Ved,
You can draw circles on a plot using the draw.circle (plotrix) function. 
If the problem is the method of drawing broken lines as suggested by Ben 
Bolker, you may be able to get broken lines on Windows by using smaller 
values in the "nv" argument. By decreasing the number of line segments 
used to draw the circle, the breaks should appear.
