[R] Double labels and scales

[Lorenzo Isella]

Dear All,
Say you want to plot, on the same figure two quantities, concentration
and temperature, both as function of the same variable.
I'd like to be able to put a certain label and scale on the y axis on
the left of the figure (referring to the temperature) and another
label and scale for the concentration on the right.
Any suggestion about what to do?
I am sure it is trivial, but I could not find what I needed on the
net. I found some reference about a plot.double function by Anne York,
but I do not think that I need anything so elaborate.
Many thanks

Lorenzo
