[R] a question on stepAIC

Hi, I am trying to use stepAIC to do forward stepwise selection for a logistic model. I did hi <- glm(melanoma ~ ., family = binomial, data=data) lo <- glm(melanoma ~ 1, family = binomial, data=data) stepAIC(lo, scope=list(upper = hi , lower = lo), direction = "forward" ) But the full m
