Extract coordinates from SpatVector objects

Source: R/stat_spat_coordinates.R
stat_spat_coordinates.Rd

stat_spat_coordinates() extracts the coordinates from SpatVector objects and summarises them to one pair of coordinates (x and y) per geometry.

Usage

stat_spat_coordinates(
  mapping = aes(),
  data = NULL,
  geom = "point",
  position = "identity",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

Arguments

mapping

Set of aesthetic mappings created by aes(). If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping.

data

A SpatVector object, see terra::vect().

geom

The geometric object to use to display the data, either as a ggproto Geom subclass or as a string naming the geom stripped of the geom_ prefix (e.g. "point" rather than "geom_point")

position

Position adjustment, either as a string naming the adjustment (e.g. "jitter" to use position_jitter), or the result of a call to a position adjustment function. Use the latter if you need to change the settings of the adjustment.

na.rm

If FALSE, the default, missing values are removed with a warning. If TRUE, missing values are silently removed.

show.legend

logical. Should this layer be included in the legends? NA, the default, includes if any aesthetics are mapped. FALSE never includes, and TRUE always includes.

You can also set this to one of "polygon", "line", and "point" to override the default legend.

inherit.aes

If FALSE, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. borders().

...

Other arguments passed on to ggplot2::stat_sf_coordinates().

Value

A ggplot2 layer

Examples

# \donttest{
cyl <- terra::vect(system.file("extdata/cyl.gpkg", package = "tidyterra"))

library(ggplot2)

ggplot(cyl) +
  stat_spat_coordinates()


ggplot(cyl) +
  geom_errorbarh(
    aes(
      geometry = geometry,
      xmin = after_stat(x) - 50000,
      xmax = after_stat(x) + 50000,
      y = after_stat(y),
      height = 10000
    ),
    stat = "sf_coordinates"
  )
