-------------------------------------------

             Summary: [R] as_arrow_array() ignores type argument for StructArrays
                 Key: ARROW-17620
                 URL: https://issues.apache.org/jira/browse/ARROW-17620
             Project: Apache Arrow
          Issue Type: Bug
          Components: R
            Reporter: François Michonneau


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.
