If you are accessing Splus using an X terminal or Sun workstation
running X, you can display graphics onscreen using the motif()
driver. Once this command has been run, you will be prompted to
place the window on the display using the mouse (a shimmering outline
of the window will appear). To test that things are working, try
the usa() command, which will display a map of the United States.
Or try:
x _ 1:1000
y _ rnorm(x,0,100) + x
plot(x,y)
title("a simple plot")
which will generate a random sample with an underlying linear
relationship.
