[jira] [Created] (ARROW-14162) [R] Simple arrange %>% head does not
respect ordering
Weston Pace created ARROW-14162:
-----------------------------------
Summary: [R] Simple arrange %>% head does not respect ordering
Key: ARROW-14162
URL: https://issues.apache.org/jira/browse/ARROW-14162
Project: Apache Arrow
Issue Type: Bug
Components: R
Reporter: Weston Pace
This was originally reported by [~jonkeane] in ARROW-13893 but that issue was covering a different topic so I am opening a new issue for this specific behavior.
