stat_cities: 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,
  ...
)

Value

a ggproto object

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.
