Don't know, at least not attached to the message through R-help.

I don't see what the problem is to construct a polygon()
Just insert x and y values of both series in an appropriate order and 
connect them at the end.

If you fail, provide fully reproducible code (we do not have efinal nor 
efinal 2 for now).

Best,
