Re: R session error (org-babel)

[Esteban Venialgo]

hi Bill,

I tried the =emacs -Q=, and still get the same problem. Before exporting the 
code, I ran this lisp from the scratch pad:

;; enable language support for R
(org-babel-do-load-languages
 'org-babel-load-languages
 '((R . t)
   (shell . t)
   (latex . t)
   (emacs-lisp . nil)))

(setq load-path '("~/.emacs.d/lisp/" "/etc/emacs" "/usr/share/emacs/site-lisp"

btw, what emacs version are you using? and OS? Also, when you exported the 
code, did you set up org-babel-load-languages to run R?

My system details are:
Gentoo Linux
I tried GNU Emacs 29.2 and 28.2
org-mode version 9.6.17

   Thanks for your help,
