stat_spatial_identity: Spatial-aware ggplot2 layers

Description

These layers are much like their counterparts, stat_identity, geom_point, geom_path, and geom_polygon, except they have a crs argument that ensures they are projected when using coord_sf. Stats are applied to the x and y coordinates that have been transformed.

Usage

stat_spatial_identity(mapping = NULL, data = NULL, crs = NULL,
  geom = "point", position = "identity", ..., show.legend = NA,
  inherit.aes = TRUE)
geom_spatial_point(mapping = NULL, data = NULL, crs = NULL, ...)
geom_spatial_path(mapping = NULL, data = NULL, crs = NULL, ...)
geom_spatial_polygon(mapping = NULL, data = NULL, crs = NULL, ...)

Arguments

mapping

An aesthetic mapping created with aes.

data

A data frame or other object, coerced to a data.frame by fortify.

crs

The crs of the x and y aesthetics, or NULL to use default lon/lat crs.

geom

The geometry to use.

position

The position to use.

...

Passed to the base ggplot2 functions geom_point, geom_path, and geom_polygon, respectively.

show.legend, inherit.aes

See layer.

Value

A ggplot2 layer.

Examples

# NOT RUN {
cities <- data.frame(
  x = c(-63.58595, 116.41214, 0),
  y = c(44.64862, 40.19063, 89.9),
  city = c("Halifax", "Beijing", "North Pole")
)

library(ggrepel)
ggplot(cities, aes(x, y)) +
  geom_spatial_point(crs = 4326) +
  stat_spatial_identity(aes(label = city), geom = "label_repel") +
  coord_sf(crs = 3857)
