Mark, The R-help list is not telepathic. I asked entirely reasonable follow-up questions intended to elicit from you a more extensive explanation of your problem.

Nor did you address mine, except to repeat them with more exclamation marks. > 2. I wish to plot.rpart the entire tree! How can I do this? What do you want to see that plot() does not show? library(rpart) fit <- rpart(Kyphosis ~ Age + Number + Start, data=kyphosis) par(mfrow=c(1,2), xpd=NA) # otherwise on some devices the text is clipped plot(fit) text(fit, use.n=TRUE) You want the "whole tree" - what is missing? That's the entire tree as shown by print(fit). > 3. I wish to predict.rpart the appropriate assignment for a single vector of > observations using the tree produced by rpart. How can I do this? newdata <- data.frame(Age=c(18, 22), Number=c(3,4), Start=c(15, 15)) predict(fit, newdata = newdata, type="class") This seems to me to provide the predicted class information for new data. What do you want that predict() is not providing? > Can anyone be of practical assistance? Of course. But we need to know *what you want*. A minimal reproducible example is handy, and I've now provided one for you because I'm feeling generous. > Mark > > -------- Original Message -------- > Subject: Re: [R] help with rpart > From: Sarah Goslee <sarah.gos...@gmail.com> > Date: Thu, July 28, 2011 1:10 pm > To: m...@statcourse.com > Cc: r-help@r-project.org > > Why repost after receiving a reply?
