[R] GLM and factor in forular

I used a GLM with a factor variable and wondered about that the first factor is missing in the results. means there is no result for Y1 Is it wrong to use factors in GLM or is there a statistical reason that there is no Y1 result ? X<-rnorm(31:40) Y<-factor(c(1:10)) glm(X~Y) Knut _
