how to start R64 from M-x R...
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.

Hi there, May be this question has been answered before, but how to start the 64 bit version inside ESS? I have successfully used C-u M-x R then "--arch=x86_64" <RT>, but remembering "--arch=x86_64" is a nuisance (for me...). Defining on Unix > alias R64 'R --arch=x86_64 &' works only from the terminal, so obviously this is an ESS thing (with elisp?) which I am not versed in.
You may ask on the ESS list, but another way around is to change the default directly in the R start script by changing
: ${R_ARCH=/`arch`}
to
: ${R_ARCH=/x86_64}
Cheers,
Simon
