This example (five groups instead of your two) may be close to what you
are looking for:
plot( rep(1:5, 20), rnorm(100))
Hopefully the ³trick² is self-evident.
(R-help doesn¹t pass on most attachments, so I can¹t look at your example)
To improve the labels I would do something like this:
plot( rep(1:5, 20), rnorm(100), xaxt='n')
axis(1, at=1:5, labels=letters[1:5])
The help pages you will want to look at include
If you haven¹t already, look at the Graphical Procedures section of the
R-intro manual that you can download from CRAN.
There is a more advanced function called ³dotchart² that creates dotplots.
It is nice if you can figure out how to use it. When I tried it, it
insisted on being fancier than what I assume you¹re looking for. I think
the above, which uses base graphics tools, is easier.
