The following in the .emacs file should do the job: (setq-default inferior-R-program-name "R32") ; unix systems (setq ess-r-versions '("R-1" "R-2" "R32" "R64"))
In my setup, I follow this with: (load "/usr/local/ess/ess-5.7.1/lisp/ess-site") Change the R32 in the initial line to R64 to make that the default.
