[R] selecting clusters of points

[Tony Long]

All:

	Are there any functions out there for selecting all the 
points in a region of a plot.  I envision something like the 
identify() function except one could circle a cloud of points (and 
perhaps a vector would be returned of the same length as the points 
plotted indicating logical membership in the circled cloud).  Perhaps 
someone has done something with the locator() function that would 
allow this (or can suggest a way I could do this).   Thanks.  Tony
