geom_sketch_qq: Sketchy quantile-quantile plot

Description

geom_sketch_qq() draws Q-Q points (the sketch analogue of ggplot2::geom_qq() / ggplot2::stat_qq()); geom_sketch_qq_line() adds the reference line (ggplot2::geom_qq_line()). Map the data to the sample aesthetic.

Usage

geom_sketch_qq(
  mapping = NULL,
  data = NULL,
  stat = "qq",
  position = "identity",
  ...,
  distribution = stats::qnorm,
  dparams = list(),
  roughness = 0.5,
  bowing = 1,
  n_passes = 2L,
  seed = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)
geom_sketch_qq_line(
  mapping = NULL,
  data = NULL,
  stat = "qq_line",
  position = "identity",
  ...,
  distribution = stats::qnorm,
  dparams = list(),
  roughness = 0.6,
  bowing = 0.5,
  n_passes = 2L,
  seed = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

Value

A ggplot2 layer object.

Arguments

mapping

Set of aesthetic mappings. Supports x, y, colour, size, alpha, and roughness.

data

Data to display.

stat

Statistical transformation (default "identity").

position

Position adjustment (default "identity").

...

Other arguments passed on to the layer.

distribution

Quantile function for the theoretical distribution. Default stats::qnorm.

dparams

List of parameters for distribution.

roughness

Non-negative roughness parameter (0 = straight). Default 1.

bowing

Non-negative bowing multiplier. Default 1.

n_passes

Number of stroke passes for the double-stroke effect. Default 2.

seed

Integer seed for reproducibility. NULL uses getOption("ggsketch.seed", 1L).

na.rm

If FALSE (default), missing values are removed with a warning.

show.legend

Logical. Should this layer be included in the legend?

inherit.aes

If FALSE, override the default aesthetics.
