R help - Jun 2007 - Asteriscs in a plot to represent approximate size of p-values

Hi,

   I need to place double and triple asterics (or
stars) to highlight very low p-values. I am using
points, for example:

points(ssdx,ssdy,pch=8,cex=.9)

   but this allows me to place only one asterisc, how
can I place 2 or 3 asteriscs?

Thank you,

Judith

   How about 
text(ssdx,ssdy,"***",cex=0.9)  ?
or 

text(ssdx,ssdy,rep("*",2,sep=""))
or 

x.eps = 0.01
points(ssdx+(0:1)*x.eps,rep(ssdy,2),pch=8,cex=0.9)

?
