Hi, I am using the glmmPQL package, and when I run the program I got the following warning messages: 1: non-integer #successes in a binomial glm! in: eval(expr, envir, enclos) 2: Singular precision matrix in level -1, block 5 What do thy mean? Thanks

I can find no such package: is this the glmmPQL function in the MASS package?

The first means what it says: you have specified the binomial glm incorrectly. Please read the posting guide and remember to send us useful information about what you were doing. The second means the model fitting process got stuck, and is more likely an error message. Given the first, no great surprise.
