Hi,
Zelig is now at version 2.6-4. And so please update it and try again. It
should work with the most recent version of Zelig.
Thanks,
Kosuke

Dear authors,
I was trying to go through your analysis example for using MatchIt and Zelig,
and after entering demo(analysis), I get the following error after a few
steps:
ate.all <- c(s.out1$qi$att.ev,
-s.out2$qi$att.ev)
Error in -s.out2$qi$att.ev : invalid argument to unary operator
and the example stops.
I am using Zelig 2.4-5 and MatchIt 2.2-11.
Don't know if this is my error or part of the package.
