Dewey Dunnington commented on ARROW-15013:
------------------------------------------
It looks like this was implemented in Python in ARROW-5554.
> [R] Expose concatenate at the R level
> -------------------------------------
>
> Key: ARROW-15013
> URL: https://issues.apache.org/jira/browse/ARROW-15013
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Dewey Dunnington
> Priority: Major
>
> Currently {{arrow::Concatenate()}} is not exposed at the R level. I imagine
> the preferred way to deal with this from a user perspective is to use
> {{ChunkedArray$create()}} for this; however, from a developer perspective
> it's very difficult to replicate this functionality. For example, another
> package using the Arrow C API might want to use the arrow R package to
> concatenate record batches complex nested types instead of implementing it
> themselves.
> Example usage in C++:
> https://github.com/apache/arrow/blob/9cf4275a19c994879172e5d3b03ade9a96a10721/r/src/r_to_arrow.cpp#L1215
