Hey all,

When exporting an org file with an R sourceblock that results in a table I get the following error: ~(wrong-type-argument number-or-marker-p nil)~.

This happens when using ~emacs -Q~ and putting the below code blocks in a test.org file; then using C-e h o to export to html.

#+begin_src emacs-lisp :results none
(require 'ob-R) ;; C-x C-e here as it's needed to run R blocks
#+end_src

#+begin_src R :exports both :colnames yes
mtcars
#+end_src

This does not seem to happen in Emacs 28.1, or in 29.0.50 with Org 9.4.6.

Debug on error shows the following:
