set type = "n" to suppress all plotting, then plot the two sets of
"scores" separately using points() or text() methods as appropriate. You
can then control exactly how the plot looks. Or plot only one set of
scores with the initial plot call and follow it up with a points() or
text() call for the sites or species as required.

Not sure what you mean by different points for different sites? How
different do you want the plotting character?
