Hi Uwe: Thanks a lot for your reply.
I contemplated the use of the predict() function but realized that it could not return what I needed (i.e., the terminal nodes and not the classes). I went back to the post of Professor Ripley (http://tolstoy.newcastle.edu.au/R/e4/help/08/07/17702.html) and did find a way to get the terminal nodes. I am showing this approach below in case other useRs face a similar problem. Many thanks. Tudor nodes <- rpart:::pred.rpart(tree.prune,rpart:::rpart.matrix(es)) where tree.prune is the rpart object and es is the estimation data set. -- View this message in context: http://r.789695.n4.nabble.com/rpart-predict-terminal-nodes-for-new-observations-tp4630104p4630508.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
