[R] Logistic Discrimination Analysis

 I've got a sample set of variables x1,...xn and a factor f that classifies
 each sample to belong to either group 0 or 1.
 If I build a model with
    m1<-glm(f~. , family=binomial(link="logit"),data=frame);
    pv<-as.vector(predict(m1))
    prob<-plogis(pv)
 does then "prob" predict the probability of a sample to belong to group 1?
 Is this equivalent to logistic discrimination analysis?
