[R] multiple lines and plot

[David Barron]

You can specify the same type parameter in either lines() or points()
that can be used in plot().  So, if you want to show points as well as
lines, use the following:

x <- c(1,2,3,4,5,6)
y <- c(3,5,2,4,1,4)
z <- c(2,3,4,3,2,1)
plot(x,y,type="b")
lines(x,z,col="red",type="b")
