You can use outline-minor-mode. The setup for *.R files is here:
For an iESS buffer, a very crude start is to add stuff like this:
(setq outline-regexp "^> ")
(setq outline-level-iESS (lambda () 1))
(setq outline-level outline-level-iESS)
to inferior-ess-mode-hook. Then with <tab> bound to outline-cycle,
I can (un)fold the output for each command with <tab> or all of them
with C-u <tab>.
Admittedly not as slick as what you suggest, but still navigating this
seems easier than scrolling thru the whole buffer.
