Wes McKinney commented on ARROW-6982:
-------------------------------------
Like ARROW-6978, wrapping {{CallFunction}} would allow dynamic invocation of
any kernel from R
> [R] Add bindings for compare and boolean kernels
> ------------------------------------------------

> Key: ARROW-6982
> URL: https://issues.apache.org/jira/browse/ARROW-6982
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Neal Richardson
> Assignee: Romain Francois
> Priority: Major
>
> See cpp/src/arrow/compute/kernels/compare.h and boolean.h. ARROW-6980
> introduces an Expression class that works on Arrow Arrays, but to evaluate
> the expressions, it has to pull the data into R first. This would enable us
> to do the work in C++ and only pull in the result.
