Hi, i have this glm: shuttle.glm.test <- glm(cbind(r,m-r)~temperature,family=binomial,data=shuttle)
and when i try to find a probability of var r (with temperature=31 and pressure=200): predict(shuttle.glm.test,data.frame(temperatura=31,pressure=200),type="response",se=T) i have this error: Warning message: 'newdata' had 1 rows but variable(s) found have 23 rows why?? thanks.
