I guess I'll chip in, since I wrote that function (which is going to be updated thoroughly in the near future -- I will probably expand it to an entire package). Have a look at MiMa at Wolfgang Viechtbauer's page. Is that what you are looking for? http://www.wvbauer.com/downloads.html

Dear List, I am (again) looking at meta-regression as a way to refine meta-analytic results. What I want to do is to assess the impact of some fixed factors on the results of a meta-analysis. Some of them may be crossed with the main factor of the meta-analysis (e. g. clinical presentation of a
