As the posting guide (you did read the posting guide, didn't you?) says, it helps if you can provide a reproducible example. Otherwise, we can only guess at what you mean. Try taking a fitted model and examining model.matrix(model) and coef(model) It should be the case that model.matrix(model) %*% coef(model) is reasonably close to fitted(model). I just saw that Dimitris wrote almost the same thing but, since I have written it, I'll mail it anyway. ______________________________________________ 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.
