I have two data sets, one is for cases, one is for controls (bigger data set
). I would likely to create a data set that has matched set (1:2 match)
based on a couple of variables.
Any one has an example using 'optmatch' function? Could you please all let
me know the data set that I should feed into the function? I am really not
good at R. Thanks!
