@bwiernik Checks look good, I think a CRAN submission can be made from this PR.

[strengejacke]

If you need any assistance for submission, let me know. The CRAN deadline is next week.

@strengejacke CRAN rejects with a NOTE because the examples in correlation.R contain the |> pipe, even though they are only shown if getRversion() >= "4.1.0".

Should we bump the minimum version up to 4.1.0?

[DominiqueMakowski]

I don't mind

Or you reply to Kurt with this gif

[bwiernik]

Is your laugh response agreement @strengejacke ? 😜

[strengejacke]

There are a few packages that import correlation. Some depend on R 2.1 (😆), which can't be met anyway. We can also fix the examples, I leave it to you what you prefer. I'm also fine with bumping to 4.1

[bwiernik]

The examples are specifically highlighting the "pipe-friendly" nature of the function, so there isn't a great way to "fix" them without removing. I'll bump.
