[R] Plotting 3 vectors on one graph.

[jim holtman]

What you want to do is to use 'plot' for the initial vector and then
"lines" to add the other two.  You will have to set the range of the
y-axis in the initial call to "plot".  The sequence would probably
look like this:

plot(a, ylim=range(a, b, c), col='black')
lines(b, col='red')
lines(c, col='green')
