Hello everyone!

Have a file like this:
--------------------------------------------
#+OPTIONS:    H:3 num:nil toc:2 \n:nil @:t ::t |:t ^:{} -:t f:t *:t TeX:t LaTeX:t skip:t d:(HIDE) tags:not-in-toc
#+BABEL: :exports both :session *R* :cache no

#+TBLNAME: Chuah07
| condition | Mean.offer |
|-----------+------------|
| 1.MMM     |      48.49 |
| 2.MMU     |      42.59 |
| 3.MUM     |      44.87 |
| 4.UMU     |      46.43 |
| 5.UUM     |      44.15 |
| 6.UUU     |      43.80 |
| MAL       |      46.28 |
| UK        |       44.1 |
| All       |      45.29 |


#+begin_src R :var data=Chuah07 :results output
str(data)
#+end_src
--------------------------------------------

If I run html export C-c C-e b, the output like this:

'data.frame':	9 obs. of  2 variables:
 $ V1: chr  "1.MMM" "2.MMU" "3.MUM" "4.UMU" ...
 $ V2: num  48.5 42.6 44.9 46.4 44.1 ...

which means the header is not recognized.

In contrast if I run C-c C-c on the block everything is fine:

#+results
: 'data.frame':	9 obs. of  2 variables:
:  $ condition : chr  "1.MMM" "2.MMU" "3.MUM" "4.UMU" ...
:  $ Mean.offer: num  48.5 42.6 44.9 46.4 44.1 ...


Also if I use :cache yes header. The html export recomputes the block.
Wouldn't it be reasonable to have the exporter take into account the :cache
header?

Thanks,
Vitalie.
