[R] JGR :: Can't Run Graphics Demo

[Alex Restrepo]

Hello:

I am using JGR 1.4, the Java GUI for R and I am trying to run the demo for 
graphics using the command:

    demo(graphics)

I keep on getting the following errror:

    Error in get(getOption("device"))() : unable to start device JavaGD


FYI, the version of Java I am using is:

     1.5.0_07-b03


Do I need to use a different version of Java?  Does anyone have any 
recommendations/suggestions?


Many Thanks In Advance:

Alex
