[-- Attachment #1.1: Type: text/plain, Size: 17936 bytes --]
I am so sorry to bother you again, but I must miss something.
When I write:
#+begin_src R :results output org :exports both
library(ascii)
options(asciiType = "org")
ascii(head(esoph))
#+end_src
The results is:
#+results:
#+BEGIN_SRC org
| | agegp | alcgp | tobgp | ncases | ncontrols |
|---+-------+-----------+----------+--------+-----------|
| 1 | 25-34 | 0-39g/day | 0-9g/day | 0.00 | 40.00 |
| 2 | 25-34 | 0-39g/day | 10-19 | 0.00 | 10.00 |
| 3 | 25-34 | 0-39g/day | 20-29 | 0.00 | 6.00 |
| 4 | 25-34 | 0-39g/day | 30+ | 0.00 | 5.00 |
| 5 | 25-34 | 40-79 | 0-9g/day | 0.00 | 27.00 |
| 6 | 25-34 | 40-79 | 10-19 | 0.00 | 7.00 |
#+END_SRC
OK, the result is surrounded by BEGIN_SRC org/END_SRC. But when I export
this, the results is exported as fontified org code. What should I do to
have this result interpreted as org markup?
