The extractor function for the fixed effects is fixef(), not coef(). Out
of curiosity, why are you using (1|ass%in%pop%in%fam)? This notation is
non-standard and does not define the nesting structure of the data.

I think you want (1|ass/pop/fam)

Subject: [R] [lme4]Coef output with binomial lmer

Dear R users  

I have built the following model

m1<-lmer(y~harn+foodn+(1|ass%in%pop%in%fam),family = "quasibinomial")

where y<-cbind(alive,dead)

where harn and foodn are categorical factors and the random 
effect is a nested term to represent experimental structure 
e.g.  Day/Block/Replicate ass= 5 level factor, pop= 2 
populations per treatment factor in each assay, 7 reps per population

The model can be family = quasibinomial or binomial

My complete lack of understanding is in retrieving the 
coefficients for the fixed effects to back-transform the 
effects of my factors on proportional survival

I get the following output:
coef(m1)
$`ass %in% pop %in% fam`
      (Intercept)      harn1     harn2   foodn2
FALSE   1.0322375 -0.1939521 0.0310434 0.810084
TRUE    0.5997679 -0.1939521 0.0310434 0.810084

Where FALSE and TRUE refer to some attribute of the random effect 

My hunch is that it refers to the Coefficients with (=TRUE) 
and without
(=FALSE) the random effects?

Any help appreciated
