Hi everyone, I use the latest version of org-mode (from github) and I update it daily. I noticed some changes recently in org-babel (ob-R). Here's a sample code to explain the problem : #+TITLE: Test export #+AUTHOR: Ahmadou H. DICKO #+PROPERTY: session *R* #+PROPERTY: cache yes #+PROPERTY: exports both #+PROPERTY: tangle yes #+OPTIONS: toc:nil * Minimal example This works quite well #+begin_src R :exports both :results output mtcars[1:2, 1:2] #+end_src I just want the output without code but I have this 'bf7c7b2c131fcf88c89639d10326a972f0ff25' before the code #+begin_src R :exports results :results output mtcars[1:2, 1:2] #+end_src I use emacs 24.3.1, org-version 8.2.5f (updated this morning) and R 3.0.2 You can find attached the sample code and output, if you have something different please let me know. Thanks for your help. -- Ahmadou H.
