lgautier opened a new issue, #39603:
URL: https://github.com/apache/arrow/issues/39603
### Describe the bug, including details regarding any error messages,
version, and platform.
`ChunkedArray` objects of type "DictionnaryType" have the method `as_vector`
(as do `ChunkedArray` objects of other types) but calling that method ends with
an error.
I am using the R package `polars` to create a problematic `ChunkedArray`.
This is how I discovered the issue and I did not find how to create a similar
ChunkedArray using the R package `arrow` alone:
```r
> require("arrow"); require("polars")
> pl_df <- polars::as_polars_df(data.frame(foo = factor(c("x", "y", "x"))))
> ar_df <- arrow::as_arrow_table(pl_df)
> ar_df$foo
ChunkedArray
<dictionary<values=large_string, indices=uint32>>
[
-- dictionary:
[
"x",
"y"
]
-- indices:
[
0,
1,
0
]
]
> ar_df$foo$as_vector()
Error: Cannot convert Dictionary Array of type
`dictionary<values=large_string, indices=uint32, ordered=0>` to R
```
`arrow` version: 12.0.0.9000
R version: 4.2.3
