[R-sig-eco] Re : Problem with Polygon

[momadou sow]

Thank you Sarah,
To answer your request, I attached my output. It seem me bad because, when I drew the only variable (MeanArea)  the shape of the figure was generally concave.I suppose that my output with polygon function would take a close shape.
Thank to you
Momadou

It's very hard to help you without:
a small reproducible example;
an idea of what you are getting vs what you expect - "does not seem
good" is not particularly informative.

Otherwise we really can't tell what's wrong.
