I think this is the wrong diagnosis.
Did you actually revert to the earlier version of ob-R.el to confirm that
this would have run correctly?
The reason I ask is that I just tried this with org-babel-R-assign-elisp
from
org-mode-a5686d87786b1d6514ec85959a2188f703346a06/lisp/ob-R.el
and got the same error. Note this:
--8<---------------cut here---------------start------------->8---
#+name: testtab2
| variable | display | unit |
|----------+----------+------|
| donor | Genotype | |
#+BEGIN_SRC emacs-lisp :var test=testtab2
(orgtbl-to-tsv test '(:fmt org-babel-R-quote-tsv-field))
#+END_SRC
#+RESULTS:
: "donor" "Genotype"
#+BEGIN_SRC emacs-lisp :var value=testtab2
;; from org-babel-R-assign-elisp
(mapcar 'length (org-remove-if-not 'sequencep value))
#+END_SRC
#+RESULTS:
| 3 |
--8<---------------cut here---------------end--------------->8---
In particular, the empty table cells are omitted even though
`value' or `test' has all lengths as 3. This results in
calling read.table ( ..., fill=FALSE) implicitly.
Not sure if the fix is to retool org-babel-R-assign-elisp or something
in org-table.el.
HTH,
