Sketchy segment and step geoms

Source: R/geom-sketch-segment.R
geom_sketch_segment.Rd

geom_sketch_segment() draws roughened straight segments from (x, y) to (xend, yend). geom_sketch_step() connects points with a hand-drawn stairstep. Sketch analogues of ggplot2::geom_segment() / ggplot2::geom_step().

Usage

GeomSketchSegment

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

GeomSketchStep

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

Format

An object of class GeomSketchSegment (inherits from Geom, ggproto, gg) of length 6.

An object of class GeomSketchStep (inherits from Geom, ggproto, gg) of length 6.

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 (0 = straight). Default 1.

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?

direction

For geom_sketch_step(): "hv" (horizontal then vertical, default) or "vh".

Value

A ggplot2 layer object.
