R help - Feb 2009 - Question about plotting data points in box plots

Hello,

I am plotting my data as side by side box plots.
Could somebody tell me how I can plot the points from which the box plots are
derived inside the box plots?
I imagine some use of the plot(x,y) function with x = the data and y = location
of box plot, but how do I distribute the points about the vertical rather than
have them show up all on one vertical axis?

Thanks in advance,

George Chen

Dear George,

You could use jitter(x) in place of x to randomly perturb the horizontal
coordinates. See ?jitter for details.

I hope this helps,
 John
