These are easily accomplished. Before doing any plotting, one must execute a ``graphics device'' command. If you are running in X-windows, X11() will pop up a graphics window where all of your plots will appear. To produce Figures 1 and 2, I used
> X11() > ts.plot(nottem) > ts.plot(hstart)
and the plots appeared in my plotting window. Note that the second plot erased the first.
