Given that, do you know how I can append data 1 to data 2 so that the combined data set will have infor from both data 1 and 2 and some missing values due to mismatch between v and (y,z). Specifically, the combined data for the first observation looks like the following: Combined data: id x y z v 1 4 a 7 mis 1 4 b 8 mis 1 4 c 9 mis 1 4 mis mis 4 1 4 mis mis 2 ......
