test-ob-R.el currently has a failing unit test: FAILED ob-session-async-R-value-drawer ((should (progn (org-babel-execute-src-block) (sleep-for 0.2) (string= (concat src-block result) (buffer-string)))) :form (progn (org-babel-execute-src-block) (sleep-for 0.2) (string= (concat src-block result) (buffer-string))) :value nil)
Here's the relevant snippet of my local.mk: # Configuration for testing # add options before standard load-path BTEST_PRE = BTEST_POST = -L /home/jack/src/ESS/lisp BTEST_OB_LANGUAGES = awk C fortran maxima lilypond octave perl python R BTEST_EXTRA = ess-site I bisected it to 1d8dbae5f883db3157cbb1c6da763dbe35811804 I did not yet investigate the nature of the breakage. I see this change was marked as a breaking change for Org 9.8. But hopefully it will still be possible to use results drawers with ob-R async eval.
