Not all that simple! It's one of those cases where you need to regain 
some control that you normally leave to the automatics.  What you can do 
is to use one of format(), formatC(), sprintf(),  to get the values  
into the format you want, xaxt="n" to get rid of the default x axis and 
then axis(1, at=value, labels=fvalue).
