Oh. 

Maybe ox-ravel would save you some steps.  It can turn *.org into *.Rmd with R, 
C/C++, and other language chunks.

For examples, see the slidify.org and demos.org files at

Thanks guys.  A combination of org-babel-goto-named-src-block and
org-babel-execute-src-block did the trick.

I am building an org template to create html presentations using the R
package xaringan.  In my case each slide is a markdown source block.
The elisp block tangles everything into a Rmd file, and the R block runs
rmarkdown::render and opens the resulting html file in a browser.

Thanks again. :)

(org-sbe myRcode)

Untested.

Re: [O] running a source code by name

[Berry, Charles]

OK, I have to note that this will also do the job that the OP requested:

#+begin_src emacs-lisp :results silent :var result=myRcode

#+end_src

although it seems a little strange to write an empty src block for its side 
effects.

I suppose I should have suggested this in the first place:

#+begin_src emacs-lisp :results silent :noweb yes
<>
#+end_src

although the return value from the noweb reference could be troublesome 
depending on what else is included in the latter src block.

Maybe wrap it in 

(save-excursion ... ) 

or use 

(org-sbe "myRcode")

or

(org-babel-ref-resolve "myRcode") 

which both can also pass :var args.

Something along the lines of:

(org-babel-goto-named-src-block "myRcode")
(org-babel-execute-src-block)

should do the job?

[O] running a source code by name

[Julian M. Burgos]

Dear list,

I have an org file with an R source code block.  I want to have a second
code block with an elisp call to run that first code.  Something like this



#+begin_src emacs-lisp :results silent :tangle no

... Some elisp code to run the "myRcode" block.

#+end_src


#+NAME: myRcode
#+beg in_src R :results silent :tangle no

... My R code here

#+end_src

What would be the best way to do it?

Many thanks,

Julian
