Hi! I'm trying to construct and plot a decision tree to class a set of only 8 objects and tried to use the rpart and tree function, but get a error message both times:
rpart: fit is not a tree, just a root tree: cannot plot singlenode tree I read in the post 'question regression trees' that rpart doesn't split a set of fewer than 20 objects...so I guess the same holds true for the tree function? My questions therefore are: How can I change the function arguments in either the rpart or the tree function so they work for a set of less than 20 objects? I looked at the function body, but since I'm new to R, I couldn't find the according argument. Or is there any other decision tree function for small datasets? Many Thanks, Patricia ______________________________________________ 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.
