Or do you mean the
missings suddenly appear after the subsampling and weren't there before?
That's it. What surprised me is that I've got missing values (empty
observations) even for the dummy variable instead of having 0 or 1.
In addition, once I set the sample on dummy=0 and want to reset it on
dummy=1 (using the --replace and --restrict flags) that's the full
sample coming out.
