But wait. If my issue was pointing to the wrong directory, I don't get why :session vs. not would make a difference? This is the exact error I get: 'R' is not recognized as an internal or external command, operable program or batch file. How does :session find R if it's not in Windows path and seems to depend on explicitly being told where to look via org-babel-R-command?
