[R] Second axis in a plot

[Juan Cuervo]

Hi to all,
First of all, I prefer to tell that I am a R-newbie,
so I apologize if this is a silly question (I have
tried looking in the manuals, but without luck).
I have two variables, y and z, that I want to plot
against x in the same plot. I have done this before,
using points() after plot(). But now the problem is
that y and z are in different units of measurement,
and their ranges are very different.
I have tried drawing a second axis with axis(), but I
found the same problem: the new axis is drawn in the
same range than the first variable plotted in the
y-axis.
I would greatly appreciate some suggestions.
Regards,
Juan L. Cuervo
