stat_automap: Attach spatial data with 'cartographer'

In ggautomap: Create Maps from a Column of Place Names

Attach spatial data with 'cartographer'

Description

Use cartographer to attach a spatial column to the data based on place names in another column. The result can then be used by ggplot2::geom_sf() or ggmapinset::geom_sf_inset().

Usage

stat_automap(
  mapping = NULL,
  data = NULL,
  geom = "sf",
  position = "identity",
  ...,
  feature_type = NA,
  na.rm = TRUE,
  show.legend = NA,
  inherit.aes = TRUE
)

Arguments

mapping, data, geom, 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.

Value

A ggplot layer

Computed variables

geometry

sf geometry column

...

limits as computed by ggplot2::stat_sf()

Examples

library(ggplot2)

events <- data.frame(
  county = c("Mecklenburg", "Carteret", "Moore", "Caldwell"),
  proportion_A = c(0.1, 0.8, 0.0, 0.6)
)

ggplot(events, aes(location = county)) +
  geom_sf(aes(fill = proportion_A), stat = "automap")

ggplot(events, aes(location = county)) +
  stat_automap(aes(fill = proportion_A)) +
  coord_automap(feature_type = "sf.nc")
