Summarise regions with pie charts

Usage

geom_pie(
  mapping = ggplot2::aes(),
  data = NULL,
  stat = "centroid_pie",
  position = "identity",
  ...,
  feature_type = NA,
  pie_radius = 1,
  proportional = FALSE,
  na.rm = TRUE,
  show.legend = TRUE,
  inherit.aes = TRUE
)

Arguments

mapping, data, stat, position, na.rm, show.legend, inherit.aes, ...: See ggplot2::geom_sf().
feature_type: Type of map feature. See feature_types() for a list of registered types. If NA, the type is guessed based on the values in feature_names.
pie_radius: Scale the side of all pies
proportional: If TRUE, scale the pies by the number of rows in each region. The radius of each pi is proportional to the count.

Value

A ggplot layer.

Aesthetics

The location aesthetic is required.

Examples

library(ggplot2)

cartographer::nc_type_example_2 |>
  ggplot(aes(location = county)) +
  geom_boundaries(feature_type = "sf.nc") +
  geom_pie(aes(fill = type), pie_radius = 0.1)
