I tried the code with the last development version of org-mode:

#+srcname: foo
#+begin_src R :session *R* :results output org replace
  library(ascii)
  options(asciiType = "org")
  ascii(head(esoph))
#+end_src

#+results: foo

 |   | 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      |

 |   | 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      |

There is no more ">", but an extra space.
But, the replace option doesn't work: results are still appended. I am not
an org-mode guru (far, far away), but I think this is because when output is
org, there is no indication about the "end" of the results.
