Hello,
I get the following error when running the example in the MatchIt package,
demo(analysis)


> ate.all <- c(s.out1$qi$att.ev, -s.out2$qi$att.ev)Error in -s.out2$qi$att.ev : invalid argument to unary operatorIn addition: Warning messages:1: In setx.default(z.out1, data = match.data(m.out1, "treat"), fn = NULL,  :

setx.default(z.out2, data = match.data(m.out1, "control"), fn = NULL,
:
  "cond" is not currently supported by this version of Zelig
