Dear Ben,
It appears that this bug was introduced sometime in 2010 -- if you roll back
to a version of Zelig from 2009 (say, version 3.4-7) -- this should give you
robust standard errors until we can patch the latest version.
Yours,
Olivia

OK, thanks. Same issue with ordered probit, so
it's probably a general
problem, not specific to the probit model.

I'll take a look when I get a chance.

Using the example in:
http://cran.r-project.org/web/packages/Zelig/vignettes/probit.pdf
If I add robust=TRUE, I get the following error:
> z.out <- zelig(vote ~ race +
educate,mode="probit",data=turnout,robust=TRUE)
Error in glm.control(robust = TRUE) : unused argument(s) (robust = TRUE)
Thoughts?
Thank you,
