plot.s2pp: Plot a spherical point pattern

In spatstat/spatstat.sphere: Point patterns on the Sphere

Plot a spherical point pattern

Description

Plot a spherical point pattern of class "s2pp" in base graphics via the globe package.

Usage

## S3 method for class 's2pp'
plot(
  x,
  ...,
  add = FALSE,
  region = !add,
  longrid = 30,
  latgrid = 30,
  region_args = list()
)

Arguments

x	Point pattern of class "s2pp" to plot.
...	parameters passed to globe::globepoints() to control view point (eye), orientation (top), and grapical parameters such as point color (col), point size (cex), point type (pch) etc.
add	Logical to add the points to existing plot.
region	Either logical to add the boundary of the "s2region" of the point pattern or a user supplied "s2region" to which the point pattern will be restricted.
longrid	Numeric defining a grid of longitude lines to be plotted if add = FALSE. Either a vector of numbers between -180 and 180 or a single numeric used as a stepsize between consecutive longitude lines. Value of zero or NULL disables longitude lines.
latgrid	Numeric defining a grid of latitude lines to be plotted if add = FALSE. Either a vector of numbers between -90 and 90 or a single numeric used as a stepsize between consecutive latitude lines. Value of zero or NULL disables latitude lines.
region_args	list of arguments passed to the plotting function for the region.

Value

NULL (invisibly)

Examples

ll <- seq(-20, 20, by = 5)
co <- expand.grid(lon = ll, lat = ll)
X <- s2pp(co, marks = co$lat)
plot(unmark(X))
plot(X)
