I had a look at this and it seems easier than I originally thought. If
I add the following to R mode hook I get filling inside roxy entries
in an adaptive fashion, seems to be what you are after?

(make-local-variable 'adaptive-fill-regexp)
(setq adaptive-fill-regexp (concat ess-roxy-str adaptive-fill-regexp))
(make-local-variable 'adaptive-fill-first-line-regexp)
(setq adaptive-fill-first-line-regexp (concat ess-roxy-str
adaptive-fill-first-line-regexp))
(make-local-variable 'paragraph-start)
(setq paragraph-start (concat "\\(" ess-roxy-str "\\)*" paragraph-start))
(make-local-variable 'paragraph-separate)
(setq paragraph-separate (concat "\\(" ess-roxy-str "\\)*" paragraph-separate))
(auto-fill-mode)
