R help - Aug 2011 - How to add horizontal lines above bar graph to display p-values?

Hi,

I would like to draw horizontal lines above a bar graph, in order to display
the p-values of a Fisher test. Here is an
example<http://thejns.org/action/showPopup?citid=citart1&id=f3-1060501&doi=10.3171%2Fped.2007.106.6.501>of
the type of display I would like to have. Is there a way to draw the
horizontal lines and write their associated p-values in R?

Thanks for you help!
