I pushed an addition to the R tests that verifies that this works from the R bindings. |
Great, thanks Ian! |

This was omitted from ARROW-13390. Note that even after this, there's work for ARROW-14105 to unify the type promotion rules and make them apply to dictionary indices/values as well. Contains some changes from ARROW-13358 and also updates case_when's promotion rules a bit.
