Swap of dodge position in ggbeeswarm::geom_beeswarm() since v3.5.1.9000

[jbengler]

Example code

ggplot(mtcars, aes(x = factor(cyl), y = disp, color = factor(am))) +
  geom_boxplot(position = position_dodge(width = 0.8)) +
  ggbeeswarm::geom_beeswarm(dodge.width = 0.8)

Output in ggplot v3.5.1

Output in ggplot v3.5.1.9000

Thanks for the report Jan!

The PR that affected this behaviour is #5923.
To summarise that PR as it relates to the issue you describe, ggplot2's internal default is to reverse the order, but the default as it comes down from users is to not reverse the order.

AFAICT, {ggbeeswarm} uses the ggplot2:::pos_dodge() function here.
This is an unexported, internal function where we do not guarantee any stability as it is not part of the API (where at least attempt some stability). For more info, see e.g. https://www.tidyverse.org/blog/2022/09/playing-on-the-same-team-as-your-dependecy/#using-.

I'm not willing to reverse course in ggplot2 because ggbeeswarm uses an internal function, so I'm going to close this issue.

Hey Teun,

thank you very much for looking into this!

I will open an issue over at {ggbeeswarm}
