Thanks to a suggestion from Stephen Eglen, I have the following solution.
On serverB, create a file ~/bin/R.magic with the contents
#!/bin/bash
module load R/3.2.3 && R
In my local .emacs, define the function
(defun RserverB ()
"Run R on serverA using the R.magic script"
(interactive)
(setq inferior-R-program-name "/home/USER/bin/R.magic")
(setq ess-directory "/ssh:USER using serverB:~/")
(R))
Now `M-x R` will work as before, and `M-x RserverB` will run R.magic on
serverB.
Note that it was not sufficient to just (setq inferior-R-program-name
"R.magic") as my PATH doesn't appear to be set when tramp opens the
connection to serverB.
Thanks Stephen!
