Image that R outputs is 7200-by-3600.

Emacs will "refuse to load" images that cannot fit in 3640-by-4320
area. Note that max-image dimensions is "tightly coupled" with the frame
size.

Instead of loading a large image, Emacs tries to create a "safe"
30-by-30 pixel area (whatver it is).
The solution is to instruct Emacs to handle higher image sizes. Just
bump the value of max-image-size. For example, add this to init file.
#+begin_src emacs-lisp
(setq max-image-size (* 2 max-image-size)) ;; modify scale
#+end_src
Side note:
==========
If you have imagemagick on your machine(s) and "identify" program is in
your load path,
#+begin_src emacs-lisp
(executable-find "identify")
#+end_src
you can configure ODT export to use imagemagick as primary source for
probing image dimensions. This you can do by adding the following to
your .emacs.
#+begin_src emacs-lisp
(setq org-export-odt-image-size-probe-method '(imagemagick force))
#+end_src
Ps: If you happen to try out imagemagick-only setting, let me know if
you run in to any issues. You will be the first person (that I know of)
to try it out.
