Hi all,

Could anybody tell me what happened to my logistic regression in R?
mylog=glm(mytraindata$V1 ~ ., data=mytraindata, family=binomial("logit"))

It generated the following error message:

Error in model.frame.default(Terms, newdata, na.action = na.action,
xlev = object$xlevels) :
  factor 'state1' has new level(s) AP

Thank you!
