[babel] apply #+TABLEFM lines during export?

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!
