I have fixed this part in the development version. For now you can put this in
your file:

     
     (defun ess-r-args-get (&optional function trim)
       (if (null function)
           (setq function (ess-r-args-current-function)))
       (when (and function
                  (or ess-current-process-name
                      (interactive-p)))
         (ess-force-buffer-current "R process to use: ")
         (mapconcat (lambda (arg) (concat (car arg) "=" (cdr arg)))
                    (cadr (ess-function-arguments function))
                    ", ")))


But don't forget to remove it when you upgrade to 16.3.
