Daniele, do you mean a factor coding the terminal node numbers for each observation? This is the `where' slot in objects returned from `ctree', for example : > airq <- subset(airquality, !is.na(Ozone)) > airct <- ctree(Ozone ~ ., data = airq, + controls = ctree_control(maxsurrogate = 3)) > factor([EMAIL PROTECTED]) [1] 5 5 5 5 5 5 5 5 3 5 5 5 5 5 5 5 5 5 5 5 5 5 5 6 3 5 6 9 9 6 5 5 5 5 5 8 9 [38] 6 8 9 8 8 8 8 5 6 6 3 6 8 8 9 3 8 8 6 9 8 8 8 6 3 6 6 8 8 8 8 9 8 9 6 6 5 [75] 3 5 6 6 5 5 6 3 8 9 8 8 8 8 8 8 8 8 9 6 6 5 5 6 5 3 5 5 3 5 5 5 6 5 5 6 5 [112] 5 3 5 5 5 Levels: 3 5 6 8 9 Hope that helps, Torsten > Hints? > > > Cheers > -- > Daniele Medri > > ______________________________________________ > R-help@stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html > > ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
