Emacs ESS won't call R

If someone could walk me through a particular problem, I'd really appreciate it... I think I know what's causing it, but I don't know how to fix it.

Problem-- Emacs ESS won't start up R.

Cause-- I've installed OpenFOAM, an open source fluids modeling kit that has it's own function called R, and executes with the letter "R". (I.e. type "R" in the command line and it tries to run an OpenFOAM function, not R). I think by installing OpenFoam, I have overwritten the previous "R" calling the language R, and so that messes with ESS trying to call R.

Environment-- I'm ssh'ing into a remote client running scientific linux where I don't have root access. I don't exactly understand what ESS is calling that is local to my account and what is not local.

Calling /usr/bin/./R from the command line starts an instance of R. How do I modify ESS such that it calls '/usr/bin/./R'?

This was the closest I could find, ESS to call different installations of R, but as far as I can tell, my system doesn't have R-1 or R-2 at all on its exec path, so I don't know how similar it is.

I had run into the same problem. Following the links and tips of Josh O'Brien, I put

;; Set default R version, (i.e. the one launched by typing M-x R <RET>)
(setq inferior-R-program-name "/usr/bin/R")

in my .emacs file. Now it works perfectly.
