Aloha all,

Is it possible to use the noweb syntax to pass LaTeX output from R  
into a latex source block?  I thought this would work, but the noweb  
expansion yields nil.

Please note that this is just a question and not a request for a  
change to org-babel.  In this particular case, the best solution for  
my workflow appears to be sending the table to a file, where I can  
tweak the results more easily and completely than I can using the  
facilities of the xtable package in R.

It does seem like a potentially useful path, though.

The following source and results blocks illustrate the situation, but  
won't run unless you have a whole.adze object in the R session.  If  
need be, I can supply an example that will stand alone.

All the best,
Tom

  Here is the output of the quantile
   function: <<r-weight-quantile()>>.

#+srcname: r-weight-quantile
#+begin_src R :session :noweb :results output
  library(xtable)
  weight <- quantile(whole.adze$weight)
  xtable(as.data.frame(weight))
#+end_src
