```For this application, you need something like
plot(dat\$x, dat\$y, type="n", xlim=range(c(dat\$x, dat\$z)),
ylim=range(c(dat\$4, dat\$v)))
points(dat\$x, dat\$y, col="red")
points(dat\$z, dat\$y, col="blue")

Similarly, you can use lines() along with lowess() to put
different coloured lines on the plot.
