It looks like ob-R implements its own result table reconstruction
instead of using the general support.  This is because R actually has a
notion of column names and row names internally.  The implementation in
ob-R does not correctly handle specified colnmaes as your example shows.

The attached patch brings ob-R closer to the using the unified general
table reconstructed used in most other languages, and fixes your problem
mentioned above.  I haven't applied it however, as it may introduce
other bugs related to specifying column names from within R.  For
example, I'm not sure that it will now correctly apply column names from
a table built entirely from within R.

Additional testing by someone more familiar with R than myself would be
greatly appreciated.

Thanks,
