In alarm-redist/ggredist: Scales, Geometries, and Extensions of 'ggplot2' for Election Mapping

Annotate a Map with Roads and Cities

Description

Clips the interstates and cities datasets to the bounding box of the map and plots them.

Usage

stat_cities(
  mapping = NULL,
  data = NULL,
  geom = ggplot2::GeomSf,
  position = "identity",
  na.rm = FALSE,
  adjust = 1,
  min_pop = 1e+05,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

stat_interstates(
  mapping = NULL,
  data = NULL,
  geom = ggplot2::GeomSf,
  position = "identity",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

Arguments

mapping	Set of aesthetic mappings created by aes()
data	The data to be displayed in this layer
geom	The geometric object to use display the data
position	Position adjustment
na.rm	if TRUE, will silently remove missing values from calculations
adjust	A multiplicative scaling factor for the default label sizes
min_pop	The minimum population a city must have had in 2006 to be shown.
show.legend	Should this layer be included in the legends?
inherit.aes	If FALSE, overrides the default aesthetics, rather than combining with them.
...	Passed onto the underlying geoms.

Value

a ggproto object

Examples

library(ggplot2)
data(oregon)

ggplot(oregon, aes(group=cd_2020)) +
  geom_district() +
  stat_interstates(size=1.4, color="#0044aa55") +
  stat_cities(geom="text", min_pop=130e3, fontface="bold", adjust=0.8) +
  scale_fill_penn82() +
  theme_map()
