Dear R list.,
I am running a script to get a compact letter display.
library(lme4)
library(multcomp)
library(gplots)
####### Mixed Effects Model #########
data <- read.table("AJmix.txt",header=TRUE, sep="\t")
attach(data)
y<-cbind(positive,negative)
treatment<-factor(treatment)
mouse<-factor(mouse)
data$obs<-1:nrow(data)
names(data)
detach(data)
attach(data)
Mixmodel<-lmer(y~treatment+(1|mouse:treatment)+(1|obs) ,family=binomial)
summary(Mixmodel)
model.mc<-glht(Mixmodel,linfct=mcp(treatment="Tukey"))
summary(model.mc, test=adjusted(type="Westfall"))
model.ci <- confint(model.mc, level= 0.95)
model.ci
par(mar=c(5,10,3,2)+.1)
plot(model.ci,main="AJ Pairwise Differences of Logit(Proportion)
OggI",
xlab="Difference in logit(Proportion) Between Treatments")
model.cld<-cld(model.mc)
par(mar=c(3,4,6,2)+.1)
plot(model.cld)
The last command resulted in a blank screen.
Here is my session and the class of similar objects.:

When I ran a very similar script with a normally distributed mixed
model it worked just fine.
I am sending this to r-help rather than the mixed effects list because
the problem is with plot(cld)
which is part of mutcomp rather than lme4. However, I can repost to
the mixed effects list if anyone thinks
that might be more appropriate.
Thanks and best wishes,
Rich

I am a Bayesian. When I see a multiple-choice question on a test and I
don't
know the answer I say "eeney-meaney-miney-moe".
