[R] convert pixels into axis coordinates in R

[P. Stencel]

Dear R users,

I've two questions:

1) Does anybody have a clue how to convert pixel from a jpeg graphic 
(e.g. something like a square of 100x100 pxs)  into axis coordinate 
values in R? 
/
//2)// Is there any possibility to extend the locator function in a way 
that //locator( ) outputs all coordinates from a plot at once, without 
clicking on the graph?

Thanks for any hints.

Regards,
P. Stencel
