Neal Richardson commented on ARROW-12137:
-----------------------------------------
Here's an example from the taxi dataset that shows a messy string column and
three kinds of queries: base R function, stringr, and an arrow_ prefixed
compute function that doesn't have an R mapping (afaik)
{code}
ds %>%
select(payment_type) %>%
mutate(
allcaps = toupper(payment_type),
chars = str_length(allcaps),
is_upper = arrow_ascii_is_upper(payment_type)
) %>%
head(10) %>%
collect()
{code}
