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.
