Sketchy curved connector

Source: R/geom-sketch-curve.R
geom_sketch_curve.Rd

Draws a hand-drawn curved segment from (x, y) to (xend, yend) - the sketch analogue of ggplot2::geom_curve(). The curve is a quadratic Bezier whose bend is controlled by curvature.

Usage

GeomSketchCurve

geom_sketch_curve(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  curvature = 0.5,
  roughness = 1,
  bowing = 1,
  n_passes = 2L,
  seed = NULL,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

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.

curvature

Amount of bend. 0 is a straight line; positive curves to one side, negative to the other. Default 0.5.

roughness

Non-negative roughness (0 = straight). Default 1. For geom_sketch_segment() this is a mappable aesthetic (map it per segment with aes(roughness = ), rescaled by scale_roughness_continuous()); for geom_sketch_step() it is a layer parameter (one path per group).

bowing

Non-negative bowing multiplier. Default 1.

n_passes

Number of stroke passes. Default 2.

seed

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

na.rm

Remove missing values silently? Default FALSE.

show.legend

Logical; include in legend?

inherit.aes

Override default aesthetics?

Value

A ggplot2 layer object.
