Hi there,

I can't seem to get a table output from running this toy example:

   #+HEADER: :results value
    #+BEGIN_SRC R
      data <- data.frame(list(a=c(1,2,3), b=c(4,5,6)))
      data
    #+END_SRC

    #+RESULTS:

The problem seems to be
org-babel-insert-result: Wrong type argument: markerp, nil

I see that the value of org-field-marker is nil in org-table.el.

I am using this version of org:
Org mode version 9.1.13 (9.1.13-elpa @
/home/user/.emacs.d/elpa/org-20180806/)

If anyone could advise it'd be great.

Thanks,
Zhihao
