Hello everybody, I am sure this is a beginners' problem which is being asked recurrently every few months, but nevertheless I wasn't able to find the answer searching through the r-help list.
So here is my problem: I would like to plot a set of points (y vs. x), a (linear) regression line through them, and on the second graph underneath the first one I would want to plot residuals vs. x. I came up with two solutions, unfortunately neither of them is fully satisfactory. First I tried with what I later learned is called traditional graphics (file norris.R). Here, the white space margins around the plots are too wide, meaning that the data in the plot are crammed. Probably I would be quite happy if I could somehow define a rectangular plotting area with its height being ~150% of its width, but I cannot prevent R from offering me a square plotting area. Next I tried a lattice package (file norris.lattice.R). Here, the margins are smaller, but the lower plot does not fit exactly under the upper one (the x-axes should match). Most likely I am not using the correct terminology (if I would have known it, I could have looked in the help pages myself, thank you :), but I hope that the attached files make more sense of what I am trying to do. Thanks in advance.
