WebFirst, you are better off combining your variables into a data.frame: df <- data.frame (y=rnorm (10), x1=rnorm (10), x2 = rnorm (10)) fit <- lm (y~x1+x2, data=df) If you do this, using you model for prediction with a new dataset will be much easier. Second, some of the statistics of the fit are accessible from the model itself, and some are ...

Yes, the fitted values are the predicted responses on the training data, i.e. the data used to fit the model, so plotting residuals vs. predicted response is equivalent to plotting residuals vs. fitted. As for your second question, the plot would be obtained by plot (lm), but before that you have to run par (mfrow = c (2, 2)).
