I read your post the other day [now the other month, as our blog is on a bit of a delay] on helping psychologists do research and thought you might be interested in our R package, “bootES”, for robust effect size calculation and confidence interval estimation using resampling techniques. The package provides one function, ‘bootES’, that makes a variety of effect size calculations fairly straightforward for researchers with limited programming experience. The majority of the implemented are not available in R or SPSS without custom coding. Kris Kirby (Williams College) and I have published a paper in Behavioral Research Methods describing the methods and providing a tutorial on use of the package: http://bit.ly/YIM6VD. We hope that it’s useful to psychologists and other social science researchers!
I haven’t tried this out but it might be of interest for some of you.
