Dewey Dunnington commented on ARROW-13165:
------------------------------------------
Adding a few notes here that were discussed on the [GitHub PR for
ARROW-13371|https://github.com/apache/arrow/pull/11690]:
- There currently is no {{StructArray$create()}}, but this might be a good
place to allow creating a struct with the additional options noted here. Note
that there isn't a static `$create()` for other array types...you can create a
`StructArray` using `Array$create()` (just like you can for the other array
types).
- After ARROW-13371, you can access {{make_struct}} by creating a nested data
frame in {{dplyr::mutate()}}, but this doesn't pass through additional options
(existing or otherwise).

> Key: ARROW-13165
> URL: https://issues.apache.org/jira/browse/ARROW-13165
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Ian Cook
> Assignee: Dragoș Moldovan-Grünfeld
> Priority: Major
>
> The {{project}} kernel creates a column of struct (equivalent to a column of
> named lists in R). Add to {{make_compute_options}} in {{compute.cpp}} so we
> can pass {{ProjectOptions}} to the {{project}} kernel.
> One practical application of the {{project}} kernel is to create a binding
> for the stringr function {{str_locate}} which returns a column of named lists.
