Solution below!

Hello, consider the following org-mode file:
=================================================
* R returning LaTeX for display
I have an R function that generates LaTeX code. I would like the
resulting LaTeX to be displayed in an inline image in the org-buffer
#+begin_src R
lf <- function() {
"\\LaTeX"
}
lf()
#+end_src
#+results:
: \LaTeX
I want the above results to actually be just like below, i.e., process
the results as LaTeX and include an image of the results. I think
org-babel can do this sort of thing, it's just escaping me how!
* If I just specify LaTeX as the input language, all works as I hope
#+begin_src latex :file latex-logo.png
\LaTeX
#+end_src[$]
The LaTeX logo is displayed properly below on my screen with the latest
inline image functions.
#+results:
[[file:latex-logo.png]]
The solution is simply to give the R src block a name, then create a new
src block of LaTeX code which calls the R src block using the noweb
syntax. Note that in my actual application the LaTeX returned is *not*
an R object like in my example, it is actually just text written to
stdout, so in my R source block I use :results output.
#+srcname: R-latex
#+begin_src R
lf <- function() {
"\\LaTeX"
}
lf()
#+end_src
#+begin_src latex :noweb yes :file latex-logo.png
<<R-latex()>>
#+end_src
Now I can preview tables produced by Hmisc's latex function in my
org-mode buffer, very nice!
