Subject: Re: Help debugging R source code block output problem with :session
Date: Sat, 29 Aug 2020 20:35:03 +0000	[thread overview]
Message-ID: <352C7149-743F-4944-ACA5-7A1242B5A3AA@health.ucsd.edu> (raw)
In-Reply-To: <87h7slgbi5.fsf@gmail.com>

This problem has been bugging people for years and previous attempts to solve it have always run up against creating more problems in the process of solving this one.

This workaround gives the same results with or without `:session "NEW"' and same as OPs first src block:

#+header: :prologue "capture.output({" :epilogue "})"
#+begin_src R :results value verbatim :session "NEW" 
print("<X> <Y> <!>")
print("one <two> three")
print("end")
#+end_src

If you do decide to dig into solving this, please be sure that remote sessions and graphical outputs are not broken.  test-ob-R.el does not cover those cases.  In fact, it is pretty short, so there are probably other things that could break without `make test' complaining.

HTH,

Chuck
