Hi all--
I have a (hopefully quick question) about formatting tabular output from
ob-R. Consider the following block:
--8<---------------cut here---------------start------------->8---
#+source: anova-example
#+BEGIN_SRC R :cache yes :exports results :colnames yes :results value
library(ez)
library(lme4)
eza <- ezANOVA(dv = .(Reaction),
sid = .(Subject),
within = .(Days),
data = sleepstudy)
print(eza$ANOVA)
#+END_SRC
--8<---------------cut here---------------end--------------->8---
This produces the following output:
--8<---------------cut here---------------start------------->8---
#+results[7e7015e41d95ed8986fb9a211a8b5c6e121ae99d]: anova-example
| Effect | DFn | DFd | SSn | SSd | F | p | p<.05 | pes |
|--------+-----+-----+-----------------+------------------+------------------+----------------------+-------+------------------|
| Days | 9 | 153 | 166235.12250176 | 151101.038615303 | 18.7026979326383 | 8.99534541600196e-21 | * | 0.52384550792003 |
--8<---------------cut here---------------end--------------->8---
That's more precision than I want in export, so I add a formula line to
the results, hoping to change the formatting of the floats. After
hitting C-u C-u C-c C-c in the table, I get the following:
--8<---------------cut here---------------start------------->8---
#+results[7e7015e41d95ed8986fb9a211a8b5c6e121ae99d]: anova-example
| Effect | DFn | DFd | SSn | SSd | F | p | p<.05 | pes |
|--------+-----+-----+-------------+-------------+---------+--------+-------+--------|
| Days | 9 | 153 | 166235.1200 | 151101.0400 | 18.7027 | 0.0000 | * | 0.5238 |
#+TBLFM: $4=$4;%.4f::$5=$5;%.4f::$6=$6;%.4f::$7=$7;%.4f::$9=$9;%.4f
--8<---------------cut here---------------end--------------->8---
That's much better! But, if I export this section to LaTeX, the formula
line is not applied and I end up with the full precision in my table.
--8<---------------cut here---------------start------------->8---
\begin{center}
\begin{tabular}{lrrrrrrlr}
Effect & DFn & DFd & SSn & SSd & F & p & p<.05 & pes \\
\hline
Days & 9 & 153 & 166235.12250176 & 151101.038615303 & 18.7026979326383 & 8.99534541600196e-21 & * & 0.52384550792003 \\
\end{tabular}
\end{center}
--8<---------------cut here---------------end--------------->8---
Is there a way to make sure that the table formula is applied to the
results block during export? Alternatively, is there another way to
reduce the precision of the numbers produced during export?
Thanks for any help!

Under the current setup, I don't know of a way to ensure that the
formula will be re-run. This may be a good place for future
(post-feature-freeze) functionality. There has also been discussion of
adding a header argument for "post-processing" code blocks which could
accept the output of the evaluated code block as input -- this might be
related.
As a work-around, I would suggest the following emacs-lisp code block.
Export of this code block will trigger the evaluation of the R code
block, and it will then trim the output of said block resulting in the
desired table precision.
--8<---------------cut here---------------start------------->8---
#+begin_src emacs-lisp :var tab=anova-example :colnames yes :cache yes
(mapcar
(lambda (row)
(mapcar
(lambda (cell) (if (numberp cell) (format "%.4f" cell) cell))
row))
tab)
#+end_src

Yes, eager to see where this goes.

I tried to customize your approach to apply to the whole buffer. This
code seems to do a nice job of changing the appearance of the tables
within the buffer, but the extra precision is still maintained on
export.
--8<---------------cut here---------------start------------->8---
#+source: format-table-floats
#+BEGIN_SRC emacs-lisp :results silent :exports none
(add-hook 'org-export-preprocess-final-hook
(lambda ()
(while (re-search-forward
"|?[ ]+\\(-?[0-9]+\\.[0-9]+\\)\\(e-\\)?[ ]+|"
nil t)
(progn
(replace-match (concat
(format "%.4f"
(string-to-number (match-string 1)))
" |"))
(org-table-align)))))
#+END_SRC
--8<---------------cut here---------------end--------------->8---
Can anyone suggest another approach that would change the precision of
floats in all tables in the buffer before export? Perhaps there's a
different hook I should be using for LaTeX export?
Thanks!

if you want to use my approach above more widely you could name the code
block say #+source:less-precision, then add :exports none to each of
your existing code blocks that output over-precise data, and for each
such block add a call of the following form
#+call: less-precision(tab=overly-precise-R-block) :exports results
which should work, but would litter your file with these call lines. I
guess this is an instance where a post-processing function specified at
the file/subtree level could potentially be useful.

Yes, the post-processing approach really seems appropriate here--
looking forward to seeing what you come up with.
In the mean time, is there definitely not any hook that applies
a) during export, and
b) after results are generated from source blocks?
If not, is it possible that adding a hook like
org-post-execution-pre-export-hook
would be a reasonable suggestion? Carsten, thoughts?
Thanks,
