[R-sig-Debian] Graphics Device; locator function

[denis brion]

I believe I remember "locator" finishes with a right click;
And, it is out of topic, but "net""books" may have a very small screen : before drawing, I usually configure my screen with "X11(height=10)" which explicitly opens the graphical device and gives a screen which is fully seeable.
