---------------------------------------
Summary: [R] Bindings for count aggregation
Key: ARROW-13501
URL: https://issues.apache.org/jira/browse/ARROW-13501
Project: Apache Arrow
Issue Type: New Feature
Components: R
Reporter: Neal Richardson
Fix For: 6.0.0
Not sure about the API on this because from what I understand from [~bkietz],
every aggregation function takes a single field ref, but group_by then count
doesn't require a field because you're counting how many rows are in each
group. (Perhaps more importantly, dplyr::n() takes no arguments, so we don't
have a field ref in our expression to start.)
