>                 Key: ARROW-14842
>                 URL: https://issues.apache.org/jira/browse/ARROW-14842
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: C, R
>            Reporter: Dragoș Moldovan-Grünfeld
>            Assignee: Yibo Cai
>            Priority: Major
>
> The error message surfaces in R like so:
> {code:r}
> decimal(0, 2)
> Error: Invalid: Decimal precision out of range: 0
> {code}
> and
> {code:r}
> decimal(100, 2)
> Error: Invalid: Decimal precision out of range: 100
> {code}
>  
> Could we improve the error message to be a bit more informative? As it is it doesn't specify what the range should be (1 to 38 for Decimal128Type, for example).
