...lt;- polymars(response=PID2$y, predictors=PID2[,1:7], startmodel=m00) > summary(m2) But I could not figure out how this works for POLYCLASS. There is an option FIT in POLYCLASS, which needs to be a POLYCLASS object though. Any suggestion or information is greatly appreciated.

I have a problem, everytime I plot in pdf, I could only draw in one page, does anyone know how to generate more than one page for example, I have 10 pics to plot in pdf, each page only could be plotted 5 pics, so how can I generate just one pdf of 2 pages, instead of two pdf Thank you -- Xiaogang Yang Sensorweb Research Laboratory http://sensorweb.vancouver.wsu.edu/ Washington State University Vancouver [[alternative HTML version deleted]]

Hi dear R-help memebers, When building a CART model (specifically classification tree) using rpart, it is sometimes obvious that there are variables (X's) that are meaningful for predicting some of the outcome (y) variables - while other predictors are relevant for other outcome variables (y's only). *How can it be estimated, which explanatory variable is "used" for which of

I have been writing out all possible model combinations by hand, and I am always worried that I am missing models or have made a mistake somewhere. It is also difficult to alter models if I want to change a term. For example,
