geom_sketch_function: Sketchy function curve

Description

Draws the curve of a function y = fun(x) with a hand-drawn stroke - the sketch analogue of ggplot2::geom_function(), built on ggplot2::stat_function().

Usage

geom_sketch_function(
  mapping = NULL,
  data = NULL,
  stat = "function",
  position = "identity",
  ...,
  fun = NULL,
  xlim = NULL,
  n = 101,
  args = list(),
  roughness = 1,
  bowing = 1,
  n_passes = 2L,
  seed = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = FALSE
)

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.

fun

Function to evaluate, or its name as a string.

xlim

Optional numeric range over which to evaluate fun; defaults to the panel x range.

n

Number of points to sample along the curve. Default 101.

args

List of extra arguments passed to fun.

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.
