[R] Polygon-like interactive selection of plotted points

Hi all,

I have the following problem/question: Imagine you have a two- 
dimensional plot, and you want to select a number of points, around  
which you could draw a polygon. The points of the polygon are defined  
by clicking in the graphics window (locator()/identify()), all points  
inside the polygon are returned as an object.

Is something like this already implemented?

Thanks a lot in advance,

Florian
