Hi all, I have been using MatchIt with success to match datasets together, usually with the "nearest" method. However I'm also running into situations where rather than match one dataset to another I just want to match to a set of target criteria. As a simple example I may want to match a group to targets such as - Male:100, Female:100, CityA: 50, CityB: 100, CityC: 50. Often this isn't possible and I simply want to get as close as possible while still hitting the overall target (200 in above case for example). Am I horribly over-thinking this? I've been experimenting with creating fake groups to match to but it seems like I may be over complicating things. Thanks in advance, Eric
