[jira] [Created] (ARROW-6982) [R] Add bindings for compare and boolean kernels

Neal Richardson created ARROW-6982:
--------------------------------------

             Summary: [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
             Fix For: 1.0.0


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.
