Neal Richardson updated ARROW-13499:
------------------------------------
Labels: query-engine (was: )
> [R] Aggregation on expression doesn't NSE correctly
> ---------------------------------------------------
>
> Key: ARROW-13499
> URL: https://issues.apache.org/jira/browse/ARROW-13499
> Project: Apache Arrow
> Issue Type: Bug
> Components: R
> Reporter: Neal Richardson
> Priority: Major
> Labels: query-engine
> Fix For: 6.0.0
>
>
> {code}
> expect_dplyr_equal(
> input %>%
> mutate(has_words = nchar(verses) < 0) %>%
> group_by(some_grouping) %>%
> summarize(all(has_words)) %>%
> arrange(some_grouping) %>%
> collect(),
> tbl
> )
> {code}
> works, but if you define the expression inline, it doesn't:
> {code}
> expect_dplyr_equal(
> input %>%
> group_by(some_grouping) %>%
> summarize(has_words = all(nchar(verses) < 0)) %>%
> arrange(some_grouping) %>%
> collect(),
> tbl
> )
> {code}
> The error you get I think means that {{base::nchar}} is being called. I'm not
> sure if this is a general issue with our nse_funcs calling other nse_funcs,
> or if this is about the way the aggregation function environment is
> constructed separately, but it's not good.
