Re: [BUG] ob-R tests fail on Emacs 27 since ESS commit 536b5b914a7 [9.7-pre (release_9.6.4-318-gcfe5e0.dirty @ /home/yantar92/.emacs.d/straight/build/org/)]

Hi Ihor,

Thanks for looking into this. I think you're right it's probably
caused by ESS now setting the width on startup. In that case you could
fix your tests by setting `options(width = )` to some hardcoded value.
You could do it via `ess-r-post-run-hook`.

Best,
Lionel
