I was wondering if anyone could give me advice regarding using the lmer
command in lme4 package to do logistic regression (mixed effects model).

I use the following command
lmer(ISH ~ArrayPathology2, random=~1|PatientID, data=HSDB4.noNA,

where ISH is outcome(0 or 1), ArrayPathology2 is the variable of
interest(factor), PatientID is random effect(factor), and HSDB4.noNA is the
complete dataframe (column names ArrayPathology2, Patient ID and ISH etc)

There are no NAs in the data.

I get the following error regardless of the R version (2.0.1, 2.1.0, or

> lmer(ISH ~ArrayPathology2, random=~1|PatientID, data=HSDB4.noNA,
Error in lmer(ISH ~ ArrayPathology2, random = ~1 | PatientID, data =
HSDB4.noNA,  :
        flist must be a non-empty list

Below is the sessionInfo() for R version 2.1.0

R version 2.1.0, 2005-04-18, i386-pc-mingw32

attached base packages:
[1] "methods"   "stats"     "graphics"  "grDevices" "utils"     "datasets"
[7] "base"

other attached packages:
        lme4 latticeExtra      lattice       Matrix
    "0.95-6"      "0.1-3"     "0.11-6"     "0.95-7"

I got the same error if I used the older version of lme4  "0.95-1" which was
mentioned in a mail to this list serve on 11th April 2005

I am using Microsoft Windows XP Professional Version 2002.

I would really appreciate any advice!!

Thanks so much
