Hello, I’m trying to fit the following model: Dependent variable: MAXDEPTH (the maximum depth reached by a penguin during a given dive) Fixed effects: SUCCESSMN (an index of the “individual quality” of a bird), STUDYDAY (the day of the study, from -5 to 20, with 0=Dec 20), and the interaction SUCCESSMN*STUDYDAY Random effect: BIRD (the bird id, as each bird is performing several dives)

Dear colleagues: I am working with binary mixed models using lme4 package and everything works fine until I try to spatialize the fitted models using grids predictors. I have used the "predict" function from RASTER package and the RSAGA functionalities, but always I have the same error: "Error in object$xlevels : $ operator not defined for this S4 class".
