>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: C++
>    Affects Versions: 5.0.0, 6.0.0
>            Reporter: Nic Crane
>            Priority: Major

> I'm writing a recipe in the cookbook about creating schemas, and when I try to create one, I get the following error:
> {{Error: NotImplemented: Extend}}
> Here's the R code which I run to get this error:
> {code:java}
> share_data <- tibble::tibble(
>   company = c("AMZN", "GOOG", "BKNG", "TSLA"),
>   price = c(3463.12, 2884.38, 2300.46, 732.39),
>   date = c("2021-09-03","2021-09-03", "2021-09-03", "2021-09-03")
> )
> share_schema <- schema(
>   company = utf8(),
>   price = decimal(precision = 1, scale = 1),
>   date = utf8()
> )
> Table$create(share_data, schema = share_schema)
> {code}
> I've tried to have a bit of a play around with parameters and a dig around to see what's going on, but I don't have much to go on.
> The schema creation itself is working fine, it's when it's passed into Table$create which is where it's causing problems. 
> I'm not sure if the error is at the C++ or R layer.  
> This is the C++ function at the R layer which is where the error is coming from: https://github.com/apache/arrow/blob/1440d5ab95c423003ecbe06372663a85cfccf769/r/src/r_to_arrow.cpp#L1327-L1342
