Sketchy count geom

Source: R/geom-sketch-count.R
geom_sketch_count.Rd

Like ggplot2::geom_count(): draws a sketch point at each (x, y) location sized by the number of observations there, via ggplot2::stat_sum(). Pair with ggplot2::scale_size_area() for honest area scaling.

Usage

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

Arguments

mapping

Set of aesthetic mappings. Supports x, y, colour, size, alpha, and roughness.

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.

Value

A ggplot2 layer object.
