[R] Alignment of axes intersection

[David Afshartous]

Agreed.  The main reason I wanted the change in alignment was that I had
three curves that were converging to a asymptote, and when I drew the
horizontal asymptote via abline(), it distorted the picture somewhat since
the line from abline() goes all the way to the y-axis.
