Dear colleagues, I am trying to perform GLM but I got the following message. m2<-glm(induction~time+plant,data=b) Error in glm.fit(x = c(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, : NA/NaN/Inf in 'y' Adem?s: Warning messages: 1: In Ops.factor(y, mu) : '-' not meaningful for factors 2: In Ops.factor(eta, offset) : '-' not meaningful for factors 3: In Ops.factor(y, mu) : '-' not meaningful for factors Do you know why it is not working? Thank you for your help, Xavier

After scrupulous textual analysis, I conclude that you have at least one NA/NaN/Inf in b$induction. There is also a hint that you should acquaint yourself with family="binomial". Sherlock On Tue, Jan 31, 2017 at 11:18 AM, CHIRIBOGA Xavier
