All right, as nobody objected to changing the redundant meaning of C-c
C-y, this is what I propose:

In script:

C-c C-y: Show *R* buffer, but don't switch to it.
C-c C-z: Switch to the end of *R*

In inferior (aka *R*):

C-c C-z returns to the most recent R-buffer. Following invocations of
C-z (or just z) will jump to next buffer in order of recency. Shift-z
will get you back in the list of R buffers. For example if you press
"C-c C-z z z Z" you will get to 2nd most recent buffer. Same story with
C-c C-y for convenience.

Currently C-c C-z and C-c C-/ are bound to the same thing in iESS,
ess-abort, which is also what C-x k will do. So not a big deal of a
