Warning: non-integer #successes in a binomial glm! (survey packages)

There’s nothing wrong, glm is just picky when it comes to specifying binomial (and Poisson) models. It warns if it detects that the no. of trials or successes is non-integral, but it goes ahead and fits the model anyway. If you want to suppress the warning (and you’re sure it’s not a problem), use family=quasibinomial instead.
