Looking at the help for scatterplot, it looks like there is a 6th option (which is probably the preferred method):
6. set the reset.par argument to FALSE in calling scatterplot as it states in the documentation for scatterplot. (still look at the help on 'xpd' argment to par if you want to add text to the margins). -- Gregory (Greg) L.
