Dewey Dunnington commented on ARROW-13766:
------------------------------------------
Some example usage maybe useful for a test:
{code:R}
library(arrow, warn.conflicts = FALSE)
library(dplyr, warn.conflicts = FALSE)
df <- tibble(a = rep(letters, 10), b = 1:260, c = 260:1)
df %>% slice_min(a, n = 5, with_ties = TRUE)
#> # A tibble: 10 × 3
#> a b c
#> <chr> <int> <int>
#> 1 a 1 260
#> 2 a 27 234
#> 3 a 53 208
#> 4 a 79 182
#> 5 a 105 156
#> 6 a 131 130
#> 7 a 157 104
#> 8 a 183 78
#> 9 a 209 52
#> 10 a 235 26
df %>% slice_min(a, n = 5, with_ties = FALSE)
#> # A tibble: 5 × 3
#> a b c
#> <chr> <int> <int>
#> 1 a 1 260
#> 2 a 27 234
#> 3 a 53 208
#> 4 a 79 182
#> 5 a 105 156
df %>% slice_min(c, n = 5)
#> # A tibble: 5 × 3
#> a b c
#> <chr> <int> <int>
#> 1 z 260 1
#> 2 y 259 2
#> 3 x 258 3
#> 4 w 257 4
#> 5 v 256 5
df %>% slice_min(c, prop = 5 / 260)
#> # A tibble: 5 × 3
#> a b c
#> <chr> <int> <int>
#> 1 z 260 1
#> 2 y 259 2

> [R] Add Arrow methods slice_min(), slice_max()
> ----------------------------------------------
>
> Key: ARROW-13766
> URL: https://issues.apache.org/jira/browse/ARROW-13766
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Ian Cook
> Priority: Major
> Labels: query-engine
> Fix For: 7.0.0
>
>
> Implement [{{slice_min()}} and
> {{slice_max()}}|https://dplyr.tidyverse.org/reference/slice.html] methods for
> {{ArrowTabular}}, {{Dataset}}, and {{arrow_dplyr_query}} objects.
> These dplyr functions supersede the older dplyr function
> [{{top_n()}}|https://dplyr.tidyverse.org/reference/top_n.html] which I
> suppose we should also consider implementing a method for.
