Aloha all, I'm trying to comprehend the possibilities created by org-babel, and would like to draw on the experience of others if I could. I recently discovered the buffer created by :session. In my case, this is an R session that I am building to track the data collection phase of a research project. I was delighted to find that it appears to have recorded everything my org file had done in that session. I have a vague idea that it might be useful to save this as a log to prove that all the little source blocks in my org file indeed were called and executed successfully. I'm wondering: do other org-babelers use the :session buffer? How? For what purpose? Any tips or advice will be appreciated. All the best, Tom Thomas S. Dye, Ph.D. T. S.
