Dear List Members,
I am running R 1.15.1 64 bit on Windows 7 64bit, and
'Zelig' version 4.0-11
'ZeligGEE' version 0.2
I wish to use Zelig to estimate mean effects from logistic regression models with
confidence intervals, and differences between mean effects with confidence intervals. Both
standard and GEE logistic regression models are operating in R packages base and geepack,
respectively, but in Zelig are returning the below messages:
z.out.1 <- zelig(cons1~rxgroup_id+herd_id, model =
"logit", data = dat)
Error in data.frame(visible = rep.int(FALSE, n2),
from = rep.int(msg, :
duplicate row.names: nobs.lm
library("ZeligGEE")
Loading required
package: gee
z.out.1 <- zelig(cons1~rxgroup_id, model =
"logit.gee", id = "herd_id", data = dat,
corstr="exchangeable")
Beginning Cgee S-function, @(#) geeformula.q 4.13
98/01/27
running glm to get initial regression estimate
(Intercept) rxgroup_idGPG + P4 rxgroup_idGPG + P4 CoSynch
-0.08068891 -0.03956022 0.36057671
Error in data.frame(visible = rep.int(FALSE, n2), from = rep.int(msg, :
duplicate row.names: nobs.default
I have run similar models in the past on previous versions of Zelig.
Look as I might, I can't find a problem with the dataframe. There are no duplicate
subject identifiers. I have tried using the subject identifier in the first column in
ascending order also. Any help on this problem would be much appreciated.

Not sure what the problem is but I wonder if the variable name should not contain
underscores.

Hi,
Try:
rownames(dat) <- NULL
then re-run the zelig step.

Dear Olivia and Kosuke,
Thank you for your prompt response. Unfortunately, the problem still remained with the
zelig functions after I made the suggested changes. Any other suggestions or steps to
diagnose the problem would be greatly appreciated.
Thanks,
Chris

Chris,
Do summary(dat) and names(dat) -- is it as you expect? Do you have
repeating rows? Eliminate them using
dat1 <- unique(dat)
Then use dat1 (rather than dat) in the zelig() step.
Note, this is not a problem with zelig, this is a problem with your data.
Best,
Olivia
