[ESS] How to start another R-process with another version of R

[Ramon Diaz-Uriarte]

(I understand this might be an unusual scenario but ...)

But I think you cannot have arbitrary names. For instance, if you have a
~/bin where you keep links to a bunch of R versions, names such as R-devel
or R-2.14 or R-2.14-my-test-number-99 will work out of the box. But if you
want to use "R-my-test-number-99", it will not (nor will "R-2-d-2" or "R-3",
etc). 


If that is needed, the following (unorthodox?) approach seems to work


(setq exec-path (append exec-path '("/home/ramon/bin")))
(unload-feature 'ess-site t)
;; these are the links that live under ~/bin
(setq ess-r-versions '("R-99" R-my-test-number-99" "R-2.14-patched" "R-2.14" "R-2.13" "R-devel")) 
(require 'ess-site)
(setq ess-use-inferior-program-name-in-buffer-name t)


Best,

R.
