Question: I am converting an existing POJO to be an JAXB compliant. Everything works fine except for one of the getter method of the pojo where I need an additional logic specific to rendering XML. However, this getter is already called somewhere within the application and I cannot modify this method's behavior.
How do I normally deal with such method name collisions? Is there a way I create a separate method just for JAXB purpose adn mark the currentmethod as XMlTransient?

Thanks

Answer: 
Not with the default plotting device as its internal model is 'static'.

There are workarounds, tough: look for example at package [playwith](http://cran.r-project.org/package=playwith), or at a Java-based device such as the [iplots](http://www.rosuda.org/iplots/) package on Simon's [rforge](http://www.rforge.net). There are also extensions like [ggobi](http://www.ggobi.org) and other on-going work (such as the Qt-based device which will in time replace ggobi) which try to make R-based graphing more dynamic. 

But the main takeaway is: not, not really -- due to the way R graphics devices are designed.
To add to existing answers: I like to use the identify() function to manually add labels just to particular points I want.
