I was just trying something simple like: #+begin_src R :exports results a <- 1+2 a #+end_src I got empty #+results block upon execution and the *Org Babel Error* (something like that) buffer had an error about the executable not being found. Adding =:session= produced results, though. Is there something new about the difference between execution with and without sessions with R? John
