Confirmed with recent Zelig and R-2.10.0.
CCing Kosuke Imai, the Zelig maintainer:
Please can you take a look at this one and additionally fix the warnings
given on your package's overview page at
http://cran.r-project.org/web/checks/check_results_Zelig.html
Please upload a fixed version with increased version number to CRAN.
Best wishes,
Uwe Ligges

hello all
I am using the R package Zelig for some tobit regression with robust
standard errors.
I have got R version 2.9.2 (2009-08-24)
and Zelig Version: 3.4-5
when i do demo(robust)
It ends like this way
data(coalition)
# Fit the model with robust standard error
user.prompt()
Press <return> to continue:
z.out3 <- zelig(Surv(duration, ciep12) ~ polar + numst2 + crisis,
model = "weibull", data = coalition, cluster = "invest", robust = TRUE)
*It is giving the following error
*Error in rowsum.default(resid(fit, "dfbeta"), cluster) :
'x' must be numeric
Please help where it is going wrong
Thanks and Regards
