When I press C-c' in an R code block to open an edit buffer with ess, on my computer, it splits the screen into two side-by-side windows, with the new window on the right showing the edit buffer, and the window on the left showing the original file.
I would like to change this behaviour in two ways.
1. I would like the window that continues to show the original file to instead show the R session in which lines from the edit buffer can be evaluated. I can manually change the buffer in this window to show me the R session but I was wondering if this can be the default behaviour.
