Add violin plot

Add violin plot

Usage

add_violin(
  plot,
  dodge_width = NULL,
  alpha = 0.3,
  saturation = 1,
  draw_quantiles = NULL,
  trim = FALSE,
  linewidth = 0.25,
  scale = "width",
  ...
)

Arguments

plot

A tidyplot generated with the function tidyplot().

dodge_width

For adjusting the distance between grouped objects. Defaults to 0.8.

alpha

A number between 0 and 1 for the opacity of an object. A value of 0 is completely transparent, 1 is completely opaque.

saturation

A number between 0 and 1 for the color saturation of an object. A value of 0 is completely desaturated (white), 1 is the original color.

draw_quantiles

If not(NULL) (default), draw horizontal lines at the given quantiles of the density estimate.

trim

If TRUE (default), trim the tails of the violins to the range of the data. If FALSE, don't trim the tails.

linewidth

Thickness of the line in points (pt). Typical values range between 0.25 and 1.

scale

if "area" (default), all violins have the same area (before trimming the tails). If "count", areas are scaled proportionally to the number of observations. If "width", all violins have the same maximum width.

...

Arguments passed on to the geom function.

Value

A tidyplot object.

Examples

study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_violin()


# Changing arguments:
study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_violin(saturation = 0.6)


study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_violin(draw_quantiles = c(0.25, 0.5, 0.75))


study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_violin(trim = TRUE)


study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_violin(linewidth = 1)
