Plot method for check model for (non-)normality of residuals

Description

The plot() method for the performance::check_normality() function.

Usage

## S3 method for class 'see_check_normality'
plot(
  x,
  type = c("qq", "pp", "density"),
  data = NULL,
  size_line = 0.8,
  size_point = 2,
  alpha = 0.2,
  dot_alpha = 0.8,
  colors = c("#3aaf85", "#1b6ca8"),
  detrend = TRUE,
  method = "ell",
  ...
)

Arguments

x	An object.
type	Character vector, indicating the type of plot. Options are "qq" (default) for quantile-quantile (Q-Q) plots, "pp" for probability-probability (P-P) plots, or "density" for density overlay plots.
data	The original data used to create this object. Can be a statistical model.
size_line	Numeric value specifying size of line geoms.
size_point	Numeric specifying size of point-geoms.
alpha	Numeric value specifying alpha level of the confidence bands.
dot_alpha	Numeric value specifying alpha level of the point geoms.
colors	Character vector of length two, indicating the colors (in hex-format) for points and line.
detrend	Logical that decides if Q-Q and P-P plots should be de-trended (also known as worm plots).
method	The method used for estimating the qq/pp bands. Default to "ell" (equal local levels / simultaneous testing - recommended). Can also be one of "pointwise" or "boot" for pointwise confidence bands, or "ks" or "ts" for simultaneous testing. See qqplotr::stat_qq_band() for details.
...	Arguments passed to or from other methods.

Value

A ggplot2-object.
