[R] as_nanoarrow_array for nanoarrow_array_stream?

[eitsupi]

I wonder collect_array_stream can be accessed via as_nanoarrow_array(<nanoarrow_array_stream>)

as_nanoarrow_array() for a nanoarrow_array_stream would involve concatenating (i.e., a copy), and that isn't something nanoarrow knows how to do. You could, as you noted, go through an R vector, but that's slow and I'd prefer to have the "chunked" case handled. The chunked case is the most common one anyway (column in an Arrow Table, polars Series).

I see, I understand. And sorry, I completely misunderstood what collect_array_stream does. It returns a LIST, not an array.......

Thanks for the quick reply!
