I face a strange problem with evaluating R source code blocks. Occasionally, they take much longer to produce the results when I try to evaluate them with C-c C-c. On the other hand, if I do C-c ‘, go to a temporary R buffer, and evaluate the code, everything works fine. In face, when I use C-c C-c, the session would sometimes get stuck. Then I have to stop the process using C-g, I find that the code had run in R, but the result was not being inserted in Org buffer.
Has anyone else faced this problem? I am on OS-X, Emacs 24, Org-mode version 8.3.4 (release_8.3.4-748-g7e320e, and ess-version: 15.09-devel [elpa: 20150913.638] Vikas
