Hi, I am a brand new user and may be my question is too simple. I have R on our (not Unix) server. I am trying to build a decision tree and the error message says "couldn't find function rpart". Does it mean I have to ask our server guy to install an additional package? Thank you, Olga [[alternative HTML version deleted]]

I think rpart is a recommended package, so you should be OK.
