Description

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
