Sketchy circle and ellipse geoms

geom_sketch_circle() draws roughened circles of radius r (data units); geom_sketch_ellipse() draws ellipses with semi-axes a (x) and b (y). Radii are in data units, so on a non-square panel a circle appears elliptical - use ggplot2::coord_equal() for true circles. These are annotation-style geoms (cf. ggforce::geom_circle()).

Usage

GeomSketchEllipse

GeomSketchCircle

geom_sketch_circle(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  roughness = NULL,
  bowing = 1,
  n_passes = 2L,
  seed = NULL,
  fill_style = "hachure",
  hachure_angle = 45,
  hachure_gap = 0.07,
  fill_weight = 0.5,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

geom_sketch_ellipse(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  roughness = 1,
  bowing = 1,
  n_passes = 2L,
  seed = NULL,
  fill_style = "hachure",
  hachure_angle = 45,
  hachure_gap = 0.07,
  fill_weight = 0.5,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping

Set of aesthetic mappings created by ggplot2::aes(). geom_sketch_circle() needs x, y, r; geom_sketch_ellipse() needs x, y, a, b.

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 = clean). A mappable aesthetic (default 1): pass a constant, or map it per shape with aes(roughness = ) (rescaled by scale_roughness_continuous()).

bowing

Non-negative bowing multiplier. Default 1.

n_passes

Number of stroke passes. Default 2.

seed

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

fill_style

Fill style when fill is mapped: "hachure", "cross_hatch", "zigzag", "scribble", "dots", "dashed", "stipple", "pencil_shade". Default "hachure".

hachure_angle

Fill line angle in degrees. Default 45.

hachure_gap

Fill line gap (npc fraction, scaled by radius). Default 0.07.

fill_weight

Stroke weight for fill lines. Default 0.5.

na.rm

Remove missing values silently? Default FALSE.

show.legend

Logical; include in legend?

inherit.aes

Override default aesthetics?

Value

A ggplot2 layer object.
