Use xaxt = 'n' in your plot call (?par for details) to suppress plotting of
the axis and then add the axis via a call to axis().

If you do a lot of plotting, you may wish to purchase a copy of Murrell's R
GRAPHICS or V&R's MASS. At the very least, do read the relevant sections of
an Introduction to R and the Reference Manual, as I believe this sort of
thing is covered there.
