[R] logistic regression - what is being predicted when using predict - probabilities or odds?

Dear gurus, I've analyzed a (fake) data set (data) using logistic regression (glm): logreg1 - glm(z ~ x1 + x2 + y, data=data, family=binomial(logit), na.action=na.pass) Then, I created a data frame with 2 fixed levels (0 and 1) for each predictor: attach(data) x1-c(0,1) x2-c(0,1) y-c(0,1)
