[R] Multiple Plotting help (lines don't always connect)

[stephen sefick]

The real data are counts of aquatic insects at distinct locations on a
river continuum on the way down a river,  so the when a point point on
the graph is missing (lost sampling equipment for that month) the
points downstream (toward the right) are valid to show a trend.
Aren't they?

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.
