ESS autodetects what versions of R are on your path using the variable
ess-r-versions is a variable defined in `essd-r.el'.
Its value is
("R-1" "R-2" "R-devel" "R-patched")
presumably if you have a binary called 'R64' on your path, then changing
this variable to include "R64" should then mean that you can do M-x R64
to get the 64 bit version.
