Hi Jack,The patch does fix that issue -- but it introduces a different bug for code blocks with ~:session~: the R block now only produces output from the last statement evaluated.
#+begin_src R :results output :exports both :session 4.0 * 3.5 log(10) # natural log log10(10) (3 + 1) * 5 3^-1 1/0 #+end_src #+results: : [1] InfWithout the ~:session header~ the output is as it was before the patch:
#+results: : [1] 14 : [1] 2.302585 : [1] 1 : [1] 20 : [1] 0.3333333 : [1] Inf -Dylan
