[R] Plotting multiple time series with variables having different units

[Bert Gunter]

If I understand you correctly, there are so many ways to do this
(ggplot2, lattice, base graphics with multiple graphs per page via
?layout,...) that I am puzzled as to how you failed to find what you
needed. Exactly what was it that you read that left you unable to do
this? Perhaps some additional links need to be created.

Incidentally, did you check the CRAN graphics task view?

Cheers,
Bert
