If you only have seven species, why not draw the label for the species
(the names() component of your data) at the species score, rather than a
colour?
plot(OBJ, display = c("sites","species"), scaling = 3, type = "n")
points(OBJ, display = "sites", scaling = 3, type = "p")
points(OBJ, display = "species", scaling = 3, type = "t")
Not tested, am away at the moment but heading home. If you are still
having trouble (and I see now why you wanted matplot) then email back and
I'll given a longer example illustrating who to build up plots by hand.
