Hi Kasper,

I have the following in my .emacs file to control that behavior:

(setq inferior-ess-same-window nil)
(setq split-height-threshold nil)
(setq split-width-threshold 0)

The first makes the inferior process open in its own window, the second and
third cause the split to be vertical rather than horizontal.
