R help - Apr 2010 - Combining ggplot2 objects and/or extracting layers

Hi,

Other then rebuilding the plots, is there any way either (1) to combine 
existing ggplot2 plots or (2) to extract a layer from an existing plot 
so that it can be added to another?

     Thanks.

Not really, although you can always pull apart the plot components.
Can you give an example of what you are trying to achieve?
