[jira] [Created] (ARROW-15460) [R] Add as.data.frame.Dataset method

Dragoș Moldovan-Grünfeld created ARROW-15460:
------------------------------------------------

             Summary: [R] Add as.data.frame.Dataset method
                 Key: ARROW-15460
                 URL: https://issues.apache.org/jira/browse/ARROW-15460
             Project: Apache Arrow
          Issue Type: New Feature
          Components: R
            Reporter: Dragoș Moldovan-Grünfeld


Started with a question from Jim Hester on Twitter:

bq. Is there a way to take an arrow::Dataset and collect all the data into a data.frame without using `dplyr::collect()`?

bq. I have a code path I just want to return a regular data.frame, but I don't really want to add a soft dplyr dependency just for this.

Twitter thread: https://twitter.com/jimhester_/status/1484624519612579841?s=21

This might also be useful for pillar/tibble. Maybe add a {{max_memory_argument}} to avoid allocating to much memory. (see suggestion from Kirill Müller)
