I ran an example using glmmADMB, and I got this error:

data(bacteria,package="MASS")
bacteria$present <- as.numeric(bacteria$y)-1
(bfit <-  glmmadmb(present ~ trt + I(week > 2), random = ~ 1 | ID,
+ family = "binomial", data = bacteria))

Error in paste0(symbol1, paste0(paste0(var, collapse = symbol2))) :
  argument "symbol1" is missing, with no default

Any ideas?
