---------------------------------------
Summary: [R] Disallow expressions that depend on order after
arrange()
Key: ARROW-13779
URL: https://issues.apache.org/jira/browse/ARROW-13779
Project: Apache Arrow
Issue Type: Improvement
Components: R
Reporter: Neal Richardson
Assignee: Neal Richardson
Fix For: 6.0.0
Because in the current ExecPlan, sorting is only done in the end (in a sink
node), we can't sort the data and then do an operation that depends on sorting
(like cumsum) without first calling compute().
