Co-developers Jake Bowers, Ben Hansen and I are happy to announce that our R packages optmatch and RItools have new homes on GitHub. We had previously been managing development on private subversion repositories and managed the projects through an ad-hoc collection of emails and text files. We are excited to make development more public and open the door to bug reports, suggestions, and patches from the wider R community.

On a related note, my article on using optmatch and RItools to block, balance test, and analyze randomized experiments has appeared in the Newsletter of the APSA Experimental Section 2.1. I published a draft of the first part of the article previously. The complete article addresses a few problems I found in the draft and walks the reader through the analysis portion of the research. I really appreciate that the editor Dustin Tingley allowed me to include raw R code in the document. The newsletter also contains articles biopolitics, using protocols to design studies, and even more on blocking. Well worth a read.
