Subject: Wrong results from R source block when returning a list

Hi

The following code block returns a wrong table / list:


#+begin_src R :results value list
list(1:10, 1:5)
#+end_src

#+RESULTS:
- (1 1)
- (2 2)
- (3 3)
- (4 4)
- (5 5)
- (6 1)
- (7 2)
- (8 3)
- (9 4)
- (10 5)

The result is actually in R:

#+begin_src R :results output
list(1:10, 1:5)
#+end_src

#+RESULTS:
: [[1]]
:  [1]  1  2  3  4  5  6  7  8  9 10
: 
: [[2]]
: [1] 1 2 3 4 5

This is likely caused by the recycling rules in R, but it is actually
wrong in the org context:

The shown result is:

#+begin_src R :results table
list(1:10, 1:5)
#+end_src

#+RESULTS:
|  1 | 1 |
|  2 | 2 |
|  3 | 3 |
|  4 | 4 |
|  5 | 5 |
|  6 | 1 |
|  7 | 2 |
|  8 | 3 |
|  9 | 4 |
| 10 | 5 |


Whil;e I would expect:

#+RESULTS:
|  1 | 1 |
|  2 | 2 |
|  3 | 3 |
|  4 | 4 |
|  5 | 5 |
|  6 |   |
|  7 |   |
|  8 |   |
|  9 |   |
| 10 |   |

I have no idea if this is a bug or wrong result due to incompatible
types (R list and org table)?

Is this mentioned in the manual?
