08/09/2017 udpate:

A package turned out to be overkill for what we needed, so I stopped developing this. You can check out all of our code and data in fully executable form on Code Ocean , where I currently work. The file ResultsStandardizeR.R has everything necessary.

This package converts various types of effect sizes into estimates of Cohen’s d, variance, and standard error. All equations are taken from Cooper, Valentine, and Hedges (2009). Currently, ResultsStandardizeR works with 1) difference in means, 2) difference in differences, 3) t-tests, 4) F-tests, 5) regression coefficients, and 6) standardized regression coefficients.
