Automatically insert R source code block?

Automatically insert R source code block?

Greetings.  Pardon my ignorance, but I'm having trouble understanding some elisp syntax.

Some time ago I asked on this list how to use the "<...<TAB>" shortcut to insert a source-code block in upper case (as: BEGIN_SRC, etc.),

Suvayu Ali responded with:


(add-to-list 'org-structure-template-alist
        '("S" "#+BEGIN_SRC ?\n\n#+END_SRC" "<src lang=\"?\">\n\n</src>"))


and this indeed worked just fine (thanks, Suvayu!).


Lately most of the source blocks I've been using have been R source blocks, so I thought I'd just modify the elisp above to stick the string " R" after the "begin_src" string.

Here's an example of something I tried:


(add-to-list 'org-structure-template-alist
        '("r" "#+begin_src R\n\n#+end_src" "<src lang=\"R\">\n\n</src>"))

The first part of this works OK; i.e., I do get:

    #+begin_src R

    #+end_src

but Emacs complains about an "org-mode fontification error" and doesn't give me an executable R source-code block.  I've tried numerous minor variations on this theme, but I don't think it's worth wasting your time by listing all of the thrashing I've done.  The solution is probably obvious to people with a decent understanding of elisp.


If you have any suggestions, please send them to me.  Thanks.

Do you have org-src-fontify-natively set to t? If so I am taking a
shot in the dark here, emacs probably doesn't know how to fontify R
source. Do you have emacs-ess installed? I would expect an error like
this if its not.

But I could be wrong here as I don't use either of emacs-ess or R.

Hopefully this was of some help.

Hi, Suvayu.  The variable org-src-fontify-natively was set to nil, but I get
the same result with it set to 't'.

I do have Emacs-ess installed.

I've been assuming that I was just messing up the syntax, but maybe there's
something deeper involved.

Thanks for your note.

Don't worry - try to insert the <s template and observe - the error is
also there (at least most of the time).
But as soon as I go into the code block, everything is fine - so I
would not worry to much, but to hope that this will be fixed?
