> ------------------------------------------------------------------

> Key: ARROW-17178
> URL: https://issues.apache.org/jira/browse/ARROW-17178
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Dewey Dunnington

> After ARROW-16444 and ARROW-16703 we will have some arrow_dplyr_query objects
> whose pipeline can't contain {{head()}} after the part that calls R code.
> This is a very big feature not to support and we need to find a workaround.
> The full-on solution is to make sure that we support an R-level
> RecordBatchReader, but there may be a workaround that we can support in the
> meantime.
