> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Neal Richardson
> Assignee: Dragoș Moldovan-Grünfeld
> Priority: Major
> Labels: good-first-issue
> Fix For: 7.0.0
>
>
> When someone calls median or quantile, we warn them that it is approximate.
> -When someone calls if_else, case_when, or coalesce on a dictionary array, we
> warn them that it will be converted to string type.- (if_else, case_when, and
> coalesce now have native support for dictionary arrays.) We probably only
> need to warn the first time. (This will also solve the issue of uncaught
> duplicate warnings in our tests, which the testthat 3e upgrade exposes.)
