Text Editing - UltraEdit and R

Hi,

I use the text editor UltraEdit.  Does anyone have any idea how to

(a) run bloc lines of R code (rather than the entire file) from within UE and

(b) execute graphics that will open up inside of R.

I can run entire files of R code from within UltraEdit just fine via a
power tool. But I would like to integrate R with UltraEdit in the same
way that is possible with Emacs.

Any advice would be hugely appreciated!  Thanks very much.

Rob
