One comment:

When I execute all the buffer (org-babel-execute-buffer), the result is:

#+begin_src R :results output org :exports both
library(ascii)
options(asciiType = "org")
ascii(head(esoph, 3))
#+end_src

#+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      |
#+END_SRC

#+results:
|   | 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 |

Then, the results is repeated twice in the buffer. I understand why, but
perhaps the "silent" option should be turned on by default for org code
blocks?
