Nicola Crane created ARROW-18199:
------------------------------------
Summary: [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
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?

library(arrow)
library(dplyr)
open_dataset("data") %>%
select(pickup_datetime, pickup_longitude, pickup_latitude
ends_with("amount")) %>%
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.
