[jira] [Created] (ARROW-14029) [R] Repair map_batches()

Ian Cook created ARROW-14029:
--------------------------------

             Summary: [R] Repair map_batches()
                 Key: ARROW-14029
                 URL: https://issues.apache.org/jira/browse/ARROW-14029
             Project: Apache Arrow
          Issue Type: Bug
          Components: R
            Reporter: Ian Cook
             Fix For: 6.0.0


The experimental {{map_batches()}} function is broken. The [one test for it|https://github.com/apache/arrow/blob/f8f2617d46e49616ab325e46542cf746293d0ebc/r/tests/testthat/test-dataset.R#L623-L636] has not been failing only because it calls the {{min()}} function which had no binding and thus triggered {{abandon_ship()}} to throw a warning and pull the data into R, preempting the error that would have happened later.
