Assignee: Nicola Crane
> [R] Misleading error message in query using across()
> ----------------------------------------------------
>
> Key: ARROW-18199
> URL: https://issues.apache.org/jira/browse/ARROW-18199
> Project: Apache Arrow
> Issue Type: Bug
> Components: R
> Reporter: Nicola Crane
> Assignee: Nicola Crane
> Priority: Critical
>
> Error handling looks like it's happening in the wrong place - a comma has
> been missed in the {{select()}} but it's wrongly appearing like it's an issue
> with {{across()}}. Can we do something to make this not happen?

> mutate(across(ends_with("amount"), ~.x * 0.87, .names = "{.col}_gbp")) %>%
> collect()
> {code}
> {code:r}
> Error in `across()`:
> ! Must be used inside dplyr verbs.
> Run `rlang::last_error()` to see where the error occurred.
