I'm not sure it's the explanation either, since external (i.e., non-session) 
evaluation works as expected. (Just remove the ":session *R*" part of the 
header, and you'll see everything is okay.) Thus, I guess this implies that R 
prompts are correctly recognized (?).
Also, an important difference between external and session eval is that session 
eval uses ESS, and external eval does not. So it *might* be an ESS-related 
issue, but since everything works fine with Org 9.5.5 and the latest ESS 
version, I wouldn't bet on that.
