> While `Arrow$create()` respects the types provided by the `type` argument,
> they are ignored when using `as_arrow_array()`. Compare the output below:
>
> {code:java}
> library(arrow, warn.conflicts = FALSE)
> dataset <- data.frame(
> a = 1,
> b = 2,
> c = 3
> )
> types <- struct(a = int16(), b = int32(), c = int64())
> as_arrow_array(
> dataset,
> type = types
> )$type
> #> StructType
> #> struct<a: double, b: double, c: double>
> Array$create(
> dataset,
> type = types
> )$type
> #> StructType
> #> struct<a: int16, b: int32, c: int64>{code}
> I have identified the bug and will submit a PR.
