> [R] Validate when creating Table with schema
> --------------------------------------------
>
> Key: ARROW-10953
> URL: https://issues.apache.org/jira/browse/ARROW-10953
> Project: Apache Arrow
> Issue Type: Bug
> Components: R
> Affects Versions: 2.0.0
> Reporter: Neal Richardson
> Assignee: Ian Cook
> Priority: Minor
> Labels: pull-request-available
> Fix For: 4.0.0

> Time Spent: 3h 10m
> Remaining Estimate: 0h
>
> This segfaults:
> {code:java}
> tab <- Table$create(data.frame(), schema = schema(a = int32()))
> as.data.frame(tab)
> {code}
> as does {{tab$a}}, i.e. just trying to extract the ChunkedArray.
> {{Table$create(data.frame(b=1), schema = schema(a = int32()))}} creates a
> Table with column named a, overwriting the "b" column name.
> {{tab <- Table$create(data.frame(b=2, c=3), schema = schema(a = int32()))}},
> i.e. providing fewer fields in the schema than there are columns in the data,
> segfaults.
> There should be some validation that the schema matches the data provided.
