Quartz was designed to work with R.app. As R warns you, Quartz  
doesn't interact with you if there is no event loop running and in  
Terminal on ESS there is none. However, I have just put together a  
hack that will help a bit - install and load CarbonEL:

As soon as you load CarbonEL, Quartz becomes usable, because the  
package installs a Carbon event loop which can driver Quartz. In  
R.app this is not needed, because R.app provides its own event loop.
