I don't think you need the ":noweb yes" as part of the setup_fu
header, as this block is not pulling in other materials.
Having used this type of setup only over the last couple of days, I've
come up with another question. It appears that the setup_fu is
executed twice ... once as it's own source block (though by itself not
need) and once as part of the second noweb block. This isn't a problem
if the execution time is small, but I'm trying to create a summary
table in Latex format from 2 million records - so the time is
considerable.
My two blocks (with some code removed for simplicity) are as follow:
#+NAME: tbl-refyear
#+BEGIN_SRC R :results silent :exports none
latex(tabular( <code remove> ))
#+END_SRC
#+BEGIN_SRC latex :noweb yes
\begin{table}[h]
\label{tbl:refyear}
\caption{Separation outcomes (death or any type of discharge) by
reference year.}
<<tbl-refyear()>>
\end{table}
#+END_SRC
I've tried :cache yes as part of the tbl-refyear source block, but
that didn't stop if from being run twice. Am I missing a suitable
header argument?
This is the only way I could find to wrap the latex table (which has
some complex formatting and hence why I've used it over just producing
a table) in a float with a caption (though I still can't properly
reference the label when I export to a PDF file).
Any thought would be greatly appreciated. TIA!
