I'm having the exact same problem. I'm running R 2.0.1 on Windows XP
(fully updated) and I've updated Zelig, MASS, and boot using the
install.packages command. My classmates discovered that the problem
"goes away" if you go back to using R 1.9.1. Unfortunately, much of our
work is done in a lab where we cannot changes versions. The lab
computers are also running XP.
Thanks,

=================================================
Could you let us know what operating system you are using? It looks like
you need to rebuild a few packages: MASS and boot. Try
install.packages("MASS")
install.packages("boot")
And then reload Zelig.
Hope this helps,
Kosuke

Dear All,
I am new to zelig but not new to R, and I use Clarify with Stata. I
think the idea behind zelig is great. The only improvement I can see
is to make zelig work with nlme (and lme4). Since now panel data and
multilevel design have become quite common, but good multilevel
software that integrate multiple imputation, simulation, and
estimation in one intergrated package is still to come (GLLAMM has
simulation capabiltiy, but it is too slow to process complicated
models or large data sets; mlwin has experimental multiple imputation
macro, but it crashes all the time).
Thanks!
