[R] How to get ``nn%'' in axis values

[s-luppescu@uchicago.edu]

I would like to make the print format of the axis value labels appear as
``nn%'' instead of just the numbers. Is there a way to do this? 

Also, the x axis value labels on my horizontal barplot are rotated 90 degrees
(perpendicular to the axis) no matter what I do. I tried las=1 but that didn't
work. Is this doable?

Thanks.
