I don't know if there is a way to use the scale relation free argument
in ggplot2 like in lattice. I have a feeling that there is not, but I
would like to make a plea for this feature. It would be nice to be
able to plot Total Inorganic Nitrogen Total Phosphorus and the ratio
of the two- the numbers on the axis are not related, but the previous
two are surely related to the last (this ratio has been suggested to
show nutrient limitation, but there is the possibility that the
concentrations of the two constituents are high enough where the ratio
is not that meaningful). Or maybe when particulate organic carbon is
related to macroinvertebrate density with scales as divergent as 1mg/L
to 1000insects/m^2 . The good parts about base graphics are that you
can do anything you want to even if it is wrong, but I'm responsible
for my actions or assumptions. ggplot is a wonderful piece of
software and most of its defaults are wonderful, but this would be
useful to me, anyway. Hadley thanks so much for this wonderful piece
of software.

make us feel like gods. We are mammals, and have not exhausted the
annoying little problems of being mammals.
