Yes. One more high-level approach to this is
matplot(x, cbind(y1,y2,y3), type = "l", main = "3 curves ...")
and maybe
legend(...)
See the respective help() pages.
A bit less highlevel with a bit more flexibility is
plot(x, ..... xlim=.., ylim=.., type = "n")
lines(x, y1, ........)
lines(x, y2, ........)
lines(x, y3, ........)
and legend() again.
Yet another even higher level approach is to work with
lattice graphics.
