Thanks Hadley -- that worked fine. However, I just noticed that when I try
to add an abline to this plot a strange error appears. First, I update the
abline function based on your advice 
http://www.nabble.com/ggplot2-geom_abline-slope-not-working--tf4770727.html#a13646422
here .

Then I try to add a line to the example I used above:

p<-ggplot(data=mydat,aes(shape=factor(site),x=predictor,y=response))

p+geom_point()+
  scale_x_continuous("Predictor Variable")+
  scale_y_continuous("Response Variable") +
  geom_abline(slope=0,intercept=5)


The error I get is:

Error in typeof(x) : object "site" not found


Is this a bug or a syntax error?
