I think sink() is the closest you can get: set R to write to a file 
before generating whatever output you want to save.

The menu item writes out the GUI text buffer; the R core doesn't know 
what's in that buffer.  Other front ends don't have a buffer at all.

Of course, we could write an Rgui-specific C function that put that text 
into an R character vector so you could do what you liked with it, but 
since sink() exists and is portable, there isn't a lot of motivation to 
do that.  This will happen automatically if we ever get around to 
defining an abstract GUI interface all controllable and configurable 
from R, but I don't know anyone working on that right now.
