Thanks for taking the time to investigate this. Upgrading to 2.2 fixed things for me. This is probably a topic for a broader discussion/list, but I hope that all authors of excellent open source R packages like MatchIt keep in mind the issues of upgrades. Many users will not install each R upgrade as it comes along. This is one of the reasons that we only require R 2.0 for our "portfolio" package. I don't have any easy solutions to how authors can both fix/improve packages to deal with the latest version of R while maintaining some backward compatability for other users, but it seems a discussion worth having, perhaps on R-devel.
