Hi Max, I see that "dotchart" does not have a "add" parameter. For the fun of it, I added this feature, you can see the source code of the new function here: https://raw.github.com/talgalili/R-code-snippets/master/dotchart.with.add.r With your example at the end of the file.
Here is a page showing the changes I've made to the original function, so to enable this feature: https://github.com/talgalili/R-code-snippets/commit/26b4104085808e6bcad49573ca2e060332467f39 This may not be the prettiest way, if someone on the list has ideas for improvement, please let me know.
