Hi Patrick,
I don't have an answer for you.
But thought it might be worth to have a look at this:
http://www.r-bloggers.com/getting-data-from-an-image-introductory-post/
Also, there was someone who presented a really simple GUI system in
useR2010. Where his code gave a GUI based on R base graphics, where it
added buttons above an image, and allowed to act on the buttons to induce an
action. I wasn't able to find his talk on the website, but it exists and
might help you with some of the coding.
Lastly I would add that I would be curious to see how you would solve your
issue. If you happen to solve it by yourself, please consider posting it
back here.
Cheers,
Tal

Hello,
I am trying to import an .eps file created with Adobe Illustrator and
plot it in a Quartz window (I am using R 2.11.1 GUI 1.34 Leopard build
32-bit (5589) on MacOSx.5.8).
I thought of using the PostScriptTrace() to convert my .eps file to
RGML, and then use readPicture to plot the file, but the first step
already fails (cf below).
I also had a look at the add.image( ) example, which does work on my
screen.
Ultimately, I would like to plot my picture and let the user click on
different parts to run different actions.
Thanks for any help or alternative ways to do this,
Patrick
