modifying the secondary Y axes title

[tdlan80]

Can you add a feature/arg to modify the secondary Y axes?
The statistical test used for multiple pairwise comparisons are now displayed as a title of the secondary Y axis. can you provide an option to either remove this secondary axes title entirely from the plot? If I set results.subtitle = F, I will lose all test results, not just the pwc test type.

And, can the name of this pairwise comparison test be displayed as the where bf.message or the caption appears?

You can pass additional arguments to {ggplot2} to customize the plot further to your liking:

library(ggstatsplot)

ggbetweenstats(
  mtcars, cyl, wt,
  ggplot.component = list(
    ggplot2::scale_y_continuous(sec.axis = ggplot2::dup_axis(name = "My custom test"))
  )
)
#> Scale for y is already present.
#> Adding another scale for y, which will replace the existing scale.

Of course, you can also use the same approach to remove that label completely by setting name = "".

And, can the name of this pairwise comparison test be displayed as the where bf.message or the caption appears?

No, because this space is already quite congested with the existing details, and adding more information here would just make it even more difficult to decode. The behaviour you are describing used to be the default behaviour but I changed to the current one precisely for the reason I mentioned.

[tdlan80]

Thanks, I should have looked into ggplot.component before. I understand that bf.message already fill-up the caption space.

And, yes, ggplot2::scale_y_continuous(sec.axis = ggplot2::dup_axis(name = " ", labels = NULL, breaks = NULL)) does work to remove the title of the duplicated axis. But, this might give off annoying warnings.

instead, this might be a better option:
ggplot.component = list( theme(axis.title.y.right = element_blank(), axis.text.y.right = element_blank(), axis.ticks.y.right = element_blank())
