That was fixed but there seemed to be a significant number of graphics and UI regressions. I've just upgraded to 20020228 to see if things were any better and within

So I have to reduce the dimension of X, and that's why I use the function #"dr" (dr package). model<- dr(Y~X,family="binomial",method="phdy"); edr<- dr.direction(model); #And now my problem: I hope that edr is a matrix constructed with linear #combinaison of X, prinipally the "index" vectors of X. But in reality it's not the #situation: library(nnet); fit<-multinom(Y~.,data=data.frame(edr)); pred<-predic...
