Babel: replace inline block with evaluation result?

Babel: replace inline block with evaluation result?

[Paul Sexton]

I have an org-mode document that uses a lot of R code (via babel). I have found
that using inline code blocks, ie src_R{...}, within org tables works
"erratically", often either causing emacs to hang during latex export, or
producing a table where random cells containing 'nil' instead of the result I
get when I manually evaluate the inline code block via C-c C-c.

I am therefore in the process of converting many of these tables back to 'plain'
org, ie replacing the inline code blocks with their results. 

My question is: is there any way to automate this? Ideally I would like to press
a key with the cursor on an inline block, and have the block replaced with its
eval result, rather than have the result appear in the minibuffer.

If you can find a minimal example which reliably reproduces this error
please do share it on the list so we can try to put together a fix.

I guess the only other option may be to create the entire table from a
code block, which is probably not practical.

The following function could be bound to a key, and should do the job if
called with the point on the src_lang portion of the inline code block.

#+begin_src emacs-lisp
  (defun replace-inline-block ()
    (interactive)
    (if (save-excursion (re-search-backward "[ \f\t\n\r\v]" nil t)
                        (looking-at org-babel-inline-src-block-regexp))
        (replace-match
         ((lambda (el) (if (stringp el) el (format "%S" el)))
          (org-babel-execute-src-block)) nil nil nil 1)
      (error "not inside of an inline source block.")))
#+end_src

Thanks Eric!

I will try to come up with a minimal example of the error I talked
about.
