I can now close the thread on -marginsplot- exiting with the error
_marg_save has a problem. Margins not uniquely identified.
r(9999);
as reported by Carla Valle-Painter <[email protected]>.
Carla had inadvertently repeated the same specification twice in an
-at()- option, e.g., -... rep78=3 rep78=3 ...-. -margins- currently
creates a separate (but equal) line in the results table for each
specification. The lines are not unique, and that caused -marginsplot-
to complain and exit. The two programs should work together better.
We will change -margins- to not produce duplicate lines. In the
interim, the workaround is to simply not ask for the same thing twice.
