Thanks for the information! Just an FYI, it makes it a little bit easier to
diagnose these issues if you supply a short reproducible code example (like the
one I'm about to paste below), rather than a screenshot of the code. However,
no problem here, as I think I know what the issue is!
In version 9.0.0 we don't yet support the ability to call functions in Arrow
with their package prefix. If you call it just as {{floor_date}} instead of
{{lubridate::floor_date()}}, this should hopefully work. I've pasted a short
reproducible example for you below.
{code:r}
library(dplyr)
library(arrow)
df <- tibble::tibble(x = as.POSIXct("2022-09-20 14:40:46 BST"))
df %>%
arrow_table() %>%
mutate(t = floor_date(x, unit = "15 min")) %>%
collect()
#> # A tibble: 1 × 2
#> x t
#> <dttm> <dttm>
#> 1 2022-09-20 14:40:46 2022-09-20 14:30:00
{code}
In version 10.0.0 we'll be supporting the ability to call functions including
the package prefix - this was completed in the dev version in ARROW-14575.
