ggspatial (version 1.1.9)

geom_spatial_rect: Projected rectangular regions

Description

If you need to plot a sf::st_bbox(), use layer_spatial() instead. While the implementation is slightly differrent, these functions are intended to behave identically to ggplot2::geom_rect() and ggplot2::geom_tile().

Usage

geom_spatial_rect(
  mapping = NULL,
  data = NULL,
  ...,
  crs = NULL,
  detail = 30,
  linejoin = "mitre",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)
geom_spatial_tile(
  mapping = NULL,
  data = NULL,
  ...,
  crs = NULL,
  detail = 30,
  linejoin = "mitre",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE
)
StatSpatialRect
StatSpatialTile

Format

An object of class StatSpatialRect (inherits from Stat, ggproto, gg) of length 4.

An object of class StatSpatialTile (inherits from StatSpatialRect, Stat, ggproto, gg) of length 4.

Arguments

mapping

An aesthetic mapping created with ggplot2::aes().

data

A data frame or other object, coerced to a data.frame by ggplot2::fortify().

...

Passed to the combined stat/geom as parameters or fixed aesthetics.

crs

The crs of the x and y aesthetics, or NULL to use default lon/lat crs (with a message).

detail

Passed to sf::st_segmentize(): the number of line segments per quadrant of the bounding box. Increase this number for a smoother projected bounding box.

linejoin

How corners should be joined

na.rm

Should missing aesthetic values be removed?

show.legend, inherit.aes

See ggplot2::layer().

Examples

library(ggplot2)
tile_df <- expand.grid(
  x = seq(-140, -52, by = 20),
  y = seq(40, 70, by = 10)
)

ggplot(tile_df, aes(x, y)) +
  geom_spatial_tile(crs = 4326) +
  coord_sf(crs = 3979)

# the same plot using geom_spatial_rect()
ggplot(
  tile_df,
  aes(xmin = x - 10, xmax = x + 10, ymin = y - 5, ymax = y + 5)
) +
  geom_spatial_rect(crs = 4326) +
  coord_sf(crs = 3979)
