Yes!!..many thanks for your help - seems the problem is still pending!
Here it is,
"Average Treatment Effect" quantities of interest are not being included in
zelig models temporarily. Simulation of these qi's will return pending a
minor update to the 'setx' function.

It appears that average treatment effects are not calculated in the
version of Zelig currently on CRAN. Note that this is a Zelig issue,
not a MatchIt issue. See the "missing features" section of
http://cran.r-project.org/web/packages/Zelig/NEWS.
