If the variable isn't registered with C-h v, then it sounds like maybe
you need to update Org-mode, and/or re-run make clean && make.

`buffer-file-name', returns the name of the file that the buffer is
visiting, so wouldn't this already be the case if the filename ends with
.R?

This minimal example with the hook defined as above works for me.  After
tangling I can jump to the *R* buffer where both x and y are defined.

--8<---------------cut here---------------start------------->8---
** tangle R and load
   :PROPERTIES:
   :tangle:   to-load.r
   :END:

#+begin_src R :comments yes
  x <- 8
#+end_src

#+begin_src R
  y <- 9
#+end_src
--8<---------------cut here---------------end--------------->8---

No problem at all, but be careful about learning too much lisp as you
may begin to grow dissatisfied with R :)
