[jira] [Updated] (ARROW-14021) [R] Bind median() to exact not approximate median

     [ https://issues.apache.org/jira/browse/ARROW-14021?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ian Cook updated ARROW-14021:
-----------------------------
    Description: ARROW-13772 binds {{median()}} to {{tdigest(q=0.5)}} which returns an approximate median. The binding issues a warning saying that the median is approximate. Once ARROW-13309 is implemented, modify the R binding to call the Arrow function that returns an exact median, and remove the warning (which is thrown by code in {{dplyr-summarize.R}}).  (was: ARROW-13772 binds {{median()}} to {{tdigest(q=0.5)}} which returns an approximate median. Once ARROW-13309 is implemented, modify the R binding to call the Arrow function that returns an exact median.)
