error in predict glmer object

I am trying to predict a glmer object with an argument newparams like this:

library(lme4)

    set.seed(123)
    df<-data.frame(id=sample(LETTERS[1:10], 50, T),
                   y=rbinom(50, 1, 0.3),
                   x1=rbinom(50, 1, 0.5),
                   x2=as.integer(rnorm(50, 40, 5)))
    df<-df[order(df$id),]

    fit<-glmer(y~x1+x2+(1|id), data=df, binomial)
    predict(fit, newparams=list(theta=getME(fit, "theta"), beta=fixef(fit)))
    Error in predict(fit, newparams = list(theta = getME(fit, "theta"), 
unused argument (newparams = list(theta = getME(fit, "theta"), beta = fixef(fit)))

May somebody here know what's the reason?

I think you should set newdata argument. This works fine :

predict(fit, newdata=df,
  newparams=list(theta=getME(fit, "theta"), beta=fixef(fit)))

PS

using your code I get a different error:

Error: inherits(fr, "data.frame") is not TRUE
