-duncan- is a user written program. The Statalist FAQ askes you to 
report where you got it from. This is important, as there are often
multiple versions of user written programs floating around in 
cyber space, and we must make sure we are talking about the same 
program, otherwise any advise we give you might well be a waste
of your and our time. I am assuming you are talking about the 
-duncan- program written by Ben Jann, which is available from SSC.

This program does return the full matrix in r(D). You won't see it
as Stata by default suppresses the display of the upper half of a
symetric matrix, but that upper half is present in the matrix r(D).

Hope this helps,
Maarten
