Need to implement slice_head(), slice_tail() - Done with slice_min(), slice_max(), and slice_sample()

[PursuitOfDataScience]

Hi,

As an experienced tidyverse user/developer who is learning Julia, I am just impressed by the Tidier package. Transferring my R knowledge to Julia is almost effortless, thanks to Tidier!

There are two very useful functions from dplyr: slice_min() and slice_max(). I think they should be included in Tidier. This link leads to the R documentation.

Thanks!

We can totally implement this by wrapping @filter() -- this is better then @arrange() followed by @slice() because both slice_min() and slice_max() need to return multiple values when there are ties.

Will work on this

Per https://x.com/alextantos1/status/1692440814448759208?s=46&t=PEX2NKcgCDoTOe3kHQFmDA, we should also add @slice_sample()

@slice_sample() is now implemented. Still need to implement the other @slice_* variants.

Finally figured out '@slice_min' and '@slice_max' and PRed them

Merged! Thank you so much @drizk1.

We’re only missing @slice_head() and @slice_tail() so will leave this issue open but will rename it.

[drizk1]

Awesome. I'll take a look at those.

Edit: I now have these both drafted to support n and prop. I'll throw in a PR a little later.

Thanks to @drizk1, @slice_head() and @slice_tail() are now implemented in v0.13.1. Will be pushed to registry shortly.
