Aloha Mike,
Eric Schulte has pushed up some patches designed to make R source block
variables accept irregular data. So, with pascals-triangle(8), for
instance, one gets a potentially useful dataframe in R:
#+NAME: sanity-check
#+HEADER: :var sc_input=pascals-triangle
#+BEGIN_SRC R
sc_input
#+END_SRC
#+RESULTS: sanity-check
| 1 | nil | nil | nil | nil | nil | nil | nil | nil |
| 1 | 1 | nil | nil | nil | nil | nil | nil | nil |
| 1 | 2 | 1 | nil | nil | nil | nil | nil | nil |
| 1 | 3 | 3 | 1 | nil | nil | nil | nil | nil |
| 1 | 4 | 6 | 4 | 1 | nil | nil | nil | nil |
| 1 | 5 | 10 | 10 | 5 | 1 | nil | nil | nil |
| 1 | 6 | 15 | 20 | 15 | 6 | 1 | nil | nil |
| 1 | 7 | 21 | 35 | 35 | 21 | 7 | 1 | nil |
| 1 | 8 | 28 | 56 | 70 | 56 | 28 | 8 | 1 |
Could you pull the development version of Org mode and see if this
solves your problem?
All the best,
Tom
