I remembered that Org knows already if point is inside a math
expression, so by looking at the source I came up with the following,
that seems to work. Sorry for the noise.
#+BEGIN_SRC emacs-lisp
(defun org-cdlatex-real-numbers ()
(interactive)
(if (org-inside-LaTeX-fragment-p)
(insert "\\mathbb{R}")
(insert "R")
))
(add-hook 'org-mode-hook
(lambda ()
(local-set-key (kbd "R")
'org-cdlatex-real-numbers
)))
#+END_SRC
