Neal Richardson created ARROW-13499:
---------------------------------------
Summary: [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
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.
