geom_violinhalf and geom_violindot not freeing scales with facet_wrap()

[ascanioalfredoa]

Hi!

I installed today "see" from CRAN (v0.6.0) [12/05/2020]

I've been trying to plot a half-violin plot using facet_wrap() while freeing the y scale. It works with the regular violin plot, but not with the geom_violinhalf or geom_violindot. Here is a reproducible example:

library(tidyverse)
library(see)

iris %>%
    pivot_longer(cols = 1:4, names_to = "variable", values_to = "values") %>%
    ggplot(aes(x = Species, y = values, fill = Species)) +
    geom_violin() +
    facet_wrap(~ variable, scales = "free_y") +
    theme_bw()

Which produces this output with the scale free on the y-axis

While the code using geom_violinhalf or geom_violindot doesn't do that:

iris %>%
    pivot_longer(cols = 1:4, names_to = "variable", values_to = "values") %>%
    ggplot(aes(x = Species, y = values, fill = Species)) +
    geom_violinhalf() +
    facet_wrap(~ variable, scales = "free_y") +
    theme_bw()

@DominiqueMakowski maybe you have an idea?

Not really, though I wonder if we should move to a less hacky way of doing half violins (for instance using ggdist), it would definitly be more robust
