You can reproduce the problem by having a data.frame (or anything else) in your
environment:
new <- data.frame(ï..VAR00001 = rep(c(TRUE,NA,FALSE), c(10,2,8)),
random=rep(1:3,len=20), clustno=rep(c(1:5),len=20),
validatedRS6=rep(0:1,len=20))
model1<- glmer(validatedRS6 ~ random + (1|clustno), data=new,
family=binomial(), nAGQ=3)
# Error in do.call(new, c(list(Class = "glmResp", family = family),
ll[setdiff(names(ll), :
# 'what' must be a character string or a function
The problem is in the call
do.call(new, list())
It finds your dataset 'new' (in .GlobalEnv), which is not a function or the
name of a function,
not the function 'new' from the 'methods' package. Rename your dataset, so you
do not
have anything called 'new' masking the one in package:methods, and things
should work.
Write to the maintainer of the package (use maintainer("lme4") for the address)
about the
problem.
