I think [ARROW-4621|https://issues.apache.org/jira/browse/ARROW-4621] might
already be solved by [these

> Key: ARROW-13886

> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Nicola Crane
> Assignee: Dragoș Moldovan-Grünfeld
> Priority: Minor
> Labels: good-first-issue
>
> Two main things we could update here:
> # The general description of what the decimal type is and is for and/or a
> link to the C++ docs - in the details section, add some explanation of what
> an Arrow {{decimal()}} type is and why it is automatically mapped to an R
> {{double}} type
> # Documentation of the params precision and scale. We could add a bit more
> information to explain what that actually means to the user, as it's not
> immediately obvious.
