[kepler-users] Question about R workflow in Mac OS X

[Dan Higgins]

Jim got it right! If you set the DISPLAY env variable in the 
enviroment.plist as suggested and have X11 running prior to Kepler, then 
the R jpeg graphics display works in Kepler when you start by double 
clicking on the .app !

Thanks for the advice Jim!
