Deal All,

Could you, please, let me know whether it is possible (and where to look for
the references and examples) to realize the following interactive graphic
routine in S+ (NT version):

I'd like to have a plot with two curves, described (in some data frames) by
(x,y) pairs. One of the curves is the reference, the other one is my working
object. I'd like to be able to take (by the mouse) any point of the working
curve and move it. The program should compute some characteristic (given by
the function f(reference, test,...)), comparing the reference with my new
working curve. I should be able to see the results somehow (on the screen,
in the file, somewhere) and continue changing the working object until I am
happy with the characteristics of this object. 

Thanks in advance for your help,
Leonid
