geom_sketch_density2d: Sketchy 2-D density contours

Description

geom_sketch_density2d() (alias geom_sketch_density_2d()) draws contour lines of a 2-D kernel density estimate with a hand-drawn stroke - the sketch analogue of ggplot2::geom_density_2d() / ggplot2::stat_density_2d(). Needs x and y aesthetics. Uses MASS (pulled in by ggplot2).

Usage

geom_sketch_density2d(
  mapping = NULL,
  data = NULL,
  stat = "density_2d",
  position = "identity",
  ...,
  roughness = 0.7,
  bowing = 0.5,
  n_passes = 2L,
  seed = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)
geom_sketch_density_2d(
  mapping = NULL,
  data = NULL,
  stat = "density_2d",
  position = "identity",
  ...,
  roughness = 0.7,
  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 created by ggplot2::aes().

data

Data to display.

stat

Statistical transformation (default "identity").

position

Position adjustment (default "identity").

...

Other arguments passed on to the layer.

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.
