Can ggplot2 adopt orphaned ggtern package?

[kevinwolz]

ggtern is a great package that builds onto ggplot2 by adding ternary plot functionality. Unfortunately, the package has not been updated in over 9 years and officially ceased to work with ggplot2 after the recent upgrade to version 3.5. See nicholasehamilton/ggtern#57.

Is ggplot2 interested in adopting ggtern in some way?

Or is someone in the community interested in forking it and make the (likely small) tweaks to get it compatible with ggplot2 3.5?

I don't have any problem rendering a ggtern plot.

The latest CRAN release dates to 2024-03-24. I think the author prefers development on bitbucket rather than github: https://bitbucket.org/nicholasehamilton/ggtern/src/master/.

officially ceased to work

I'm unclear where the author has stated this.

Is ggplot2 interested in adopting ggtern in some way?

It is ggplot2's policy to limit new features to either easy to maintain features or widely useful improvements. Ternary plots are rather specialised and, I imagine, hard to maintain. For these reasons, I'd say it is unlikely that ggplot2 will adopt ggtern.

Well would you look at that. Bitbucket. I wish the author would have posted on their GitHub or shut that repo down. Looks like that solves all the problems! Thank you!
