--------------------------------
Assignee: Ian Cook (was: Nicola Crane)
> [R] Binding for median() and quantile() aggregation functions
> -------------------------------------------------------------
>
> Key: ARROW-13772
> URL: https://issues.apache.org/jira/browse/ARROW-13772
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Nicola Crane
> Assignee: Ian Cook
> Priority: Critical
> Labels: kernel, pull-request-available
> Fix For: 6.0.0
>
> Time Spent: 3.5h
> Remaining Estimate: 0h
>
> Another aggregate function we’ll need to look at is median().
> That should in theory map to the existing quantile kernel and the
> hopefully-coming-soon hash_quantile kernel with q = 0.5, but that will not
> work right now for several reasons (see
> https://issues.apache.org/jira/browse/ARROW-13309).
> However we also have a pair of
> approximate quantile kernels: tdigest and hash_tdigest that we could map
> median() to.
