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 ?plot ?par 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. -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 11/24/14, 1:08 AM, "Juan Scheun" <jsch...@zoology.up.ac.za> wrote: >Morning everyone > > >I am relatively new to R and although there are tons of "how to" websites, >some are just way over my head.
