Hi Rainer & list,

I've set the following property for the subtree that both code blocks are
in:

:header-args+: :eval no

but this results in no execution of either block
​​
.

I noticed in a separate thread (
https://lists.gnu.org/archive/html/emacs-orgmode/2014-09/msg00547.html)
​ that there is also :float header argument.​ The manual seems to indicate
that it only applies to org tables (exported to latex) - I've tried using
it on the original source block that produces a latex table as output,
which of course didn't work.

But ... if it did, that is,
if this float (and placement) header argument was utilised by the latex
source block, and so wrapped the output in a float (with optional caption
​ & label​
), then this
​c​ould
 circumvent the need for the second noweb source block.

The alternative mentioned by Chuck Berry is the xtable function (in R) (
https://lists.gnu.org/archive/html/emacs-orgmode/2014-09/msg00519.html). I
just tried it and am happy to share that it does created the whole output
in one go, i.e. it does exactly what I need, including table float, caption
and label. Now I just got to sort out how to created the tables without the
use of tabular ...

Thanks to all for your help!

Cheers,

Andreas
