Vikas,
Copy the src-block at bottom to a *.org file or org-mode buffer. Then
execute it with `C-c C-c y'.
You should see
#+RESULTS:
: org-babel-comint-eval-invisibly-and-wait-for-file
appear afterwards.
Then try running your R code to see if it works reliably.
Does that seem to fix it?
If not, please check the session buffer to see if there were any
warnings or errors.
Chuck
