[R] ggplot2 scale relation free

[stephen sefick]

no, no, I want to facet on a variable and then have the plots stacked
on top of each other with different scales.  I have grown quite fond
of not having four different things on a plot all with different
scales- it is quite confusing.  I may send you along an example when I
get to that point.  I have about two weeks worth of work yet before
all of the insects are done. thank you for the offer.
thanks agian

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
