Look at:

  Use ESS to step through evaluation line-by-line

    Use C-c ' to visit the edit buffer for your code block
    Use ess-eval-line-and-step to evaluate each line in turn
 
ess-eval-line-and-step is usually bound to C-c C-n

I guess that is possible to use the same R session by configuring the
session arguments and/or the ESS settings but I have not done it yet.

If you do not have ESS you can try a more lightweight solution with
isend-mode.

Best,
Daniele
