Hi, I have set up two monitors. I am using windows XP. I would like to keep one window- command line in one monitor and the script and graphs in the second monitor. How do I set it up? It works for word documents simply by dragging the document. It does not work if I drag and drop the scripts window. Is R not compatible for this? Thanks.
