Jonathan, why is -merge- or -append- not applicable to your situation?
Can you provide some example data that shows the problem?
What is your key variable in addition to pid? That is, what is your
within-id identifier (subobservation), e.g., year or wave?
Are there few or many variables in each of the two datasets (asked to
figure out whether merge or append might be better)?
You can look into -joinby- and -cross- if you instead are trying to
create pairwise combinations.
