["Nicola Crane (Jira)" <ji...@apache.org>]

Nicola Crane created ARROW-13985:
------------------------------------

             Summary: [R] Warning/error if dplyr::summarise() called when column is renamed but the original should be displayed in output too
                 Key: ARROW-13985
                 URL: https://issues.apache.org/jira/browse/ARROW-13985
             Project: Apache Arrow
          Issue Type: Improvement
          Components: R
            Reporter: Nicola Crane


I was playing around with contrived examples to come up with tests for the dplyr::distinct() implementation, and tried this code:

{code:java}
input %>% Table$create() %>%
       group_by(some_grouping, false, lgl) %>%
       summarise(x = lgl) %>%
       collect()
{code}

but got this warning/error message:

{{Warning: Error in .f(.x[[i]], ...) : attempt to apply non-function; pulling data into R}}
