multiple secondary axes
In the zoo package the example section of ?plot.zoo has an example. The same technique works even if you are not using zoo. On Wed, Jan 14, 2009 at 4:29 AM, Kirsten Thonicke

Dear R experts, I want to plot a line chart with another secondary axis placed right to the standard secondary axis which one can access with the axis command, so that the data lines are seen in the same plot. Is there any way to do this in R? Many thanks, Kirsten.
