Ian Cook updated ARROW-14021:
-----------------------------
Description: ARROW-13772 binds {{quantile()}} to {{tdigest()}} which
returns approximate quantiles and binds {{median()}} to
{{approximate_median()}} which returns an approximate median. The bindings
issue a warning saying that the median/quantile is approximate. Once
ARROW-13309 is implemented, modify the binding to call Arrow functions that
returns exact quantiles and medians, and remove the warnings. (was:
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}}).)
