I don't know if I understand exactly what you would like to be able to
do.  But this is how I would go about it if I understand you
correctly.  I would make a data frame out of the points and the code a
dummy variable for the control sites in another column.  The I would
use ggplot2 to use the dummy variable a shape, color, or size...

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.
