Hi, I am looking for some function implemented in R for classification, which has an option to allow me to assign sample weights in learning process? Implementation of a wrapper function is possible but I am curious if it already exists somewhere. Thanks, -- Weiwei Shi, Ph.D Research Scientist

Almost all methods I know of do: logistic regression, neural nets, classification trees, PPR Have you looked at the help pages for any of these? On Tue, 23 Jan 2007, Weiwei Shi wrote: Hi, I am looking for some function implemented in R for classification, which has an option to allow

Just checked ?lrm ?nnet ?rpart ?ppr thanks. but wondering if the last one can do classification? On 1/23/07, Prof Brian Ripley [EMAIL PROTECTED] wrote: Almost all methods I know of do: logistic regression, neural nets, classification trees, PPR Have you looked at the help pages for
