Hi Simon, Yes I agree with you on the definition of IG (selection, data query, ...), but I only meant to respond to Oleg's "R lacks functionality that would allow displaying of interactive plots with two distinct functionalities: zooming and panning." I thought that was just a problem to adjust the x and y limits, so I posted the "chewing gum" :-)
For Oleg: sorry I forgot to mention that currently getGraphicsEvent() only works for Windows screen display.
