[GitHub] [arrow] paleolimbot opened a new pull request, #14519: ARROW-18043: [R] Properly instantiate empty arrays of extension types in Table__from_schema
paleolimbot opened a new pull request, #14519:
URL: https://github.com/apache/arrow/pull/14519
This PR supports the following:
``` r
library(arrow, warn.conflicts = FALSE)
#> Some features are not enabled in this build of Arrow. Run `arrow_info()` for more information.
schema_with_ext_type <- schema(
x = int32(),
y = vctrs_extension_type(integer())
)
as_arrow_table(schema_with_ext_type)
#> Table
#> 0 rows x 2 columns
#> $x <int32>
#> $y <integer(0)>
```

It's a little bit cheating, though, because the previous approach is more true to what `ChunkedArray::MakeEmpty()` does. Is there a downside here to creating a `ChunkedArray` with zero chunks (as opposed to a `ChunkedArray()` with one empty chunk)? If there is we can probably work around it via creating an empty array of the storage type and wrapping it.
