Thanks for the suggestions. I needed it to be a little more generic to capture lm models where the dataset may or may not have been attached. Also, if they specified any interaction effects, I needed to capture them, so model.frame wouldn't work. With Henrique's help, I did this:
new<-model.matrix(lm.out) new[,1]<-lm.out$model[,1] This seems to do what I need. ********************************************************* Dr. J.
