R help - Nov 2009 - how to combine the boxplot and dotchart together?

Hi all:
Suppose there're 3 groups,and I wanna compare the result of the 3 groups.
I've drawn a boxplot.But I wanna show the actural data points of each group
at the same time.In other words I wanna combine the boxplot and dotchart
together.
How can I do it?
 
Thanks a lot!
 
My best.

Perhaps like this:

   boxplot(Sepal.Length ~ Species, data = iris)
   points(Sepal.Length ~ Species, data = iris)

or, if you have overlapping points:

   points(Sepal.Length ~ jitter(rep(1:3, each=50),
                                amount=.05),
          data=iris)
