geom_spatial_rect function

Projected rectangular regions

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(). data

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.

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

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)
