Neal Richardson updated ARROW-7796: ----------------------------------- Summary: [R] write_* functions should invisibly return their inputs (was: arrow::write_* functions should invisibly return their inputs) > [R] write_* functions should invisibly return their inputs > ---------------------------------------------------------- > > Key: ARROW-7796 > URL: https://issues.apache.org/jira/browse/ARROW-7796 > Project: Apache Arrow > Issue Type: Improvement > Components: R > Affects Versions: 0.15.1 > Environment: Windows 10, R 3.6.2 > Reporter: Sam Albers > Priority: Minor > > > I am wondering if you'd consider a slight change to what is returned by the > write_* functions. In \{readr} the write functions return its input which is > very useful for saving intermediate objects within a pipeline. I'd be happy > to take this on and submit as a pull request.
