R help - Feb 2010 - NMDS ordination

Hi

Im currently trying to plot my NMDS data together with fitted variables
(envfit funct) on an ordination plot. The plot function shows two
displays="sites" and "sp". I was wondering how to plot it so
that the sites
come up as different points for different sites but the species come up as
actual names? It looks a little busy at the moment with everything in.

Please provide an example. I.e. working code creating the plot as you have it at
the moment. Include an example data set and be explicit about what packages are
needed. Don't post a large data set -- just create a minimal example
demonstrating the problem you are having.

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?
