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()
.
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
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.
An aesthetic mapping created with ggplot2::aes()
.
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.
The crs of the x and y aesthetics, or NULL to use default lon/lat crs (with a message).
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.
How corners should be joined
Should missing aesthetic values be removed?
See ggplot2::layer()
.
