Re: [R] Error message glmer using R: “ 'what' must be a character string or a function”

You can reproduce the problem by having a data.frame (or anything else) in your environment: new - data.frame(ï..VAR1 = 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),
