In rubak/spatstatsphere: Point patterns on the sphere for spatstat package

Description

Import spatstat

Usage

spp(lat, long, domain = NULL, ..., check = TRUE)

Arguments

lat	Numeric. Latitudes of points.
long	Numeric. Longitude of points.
domain	Domain where the points occur. Object of class "sphericaldomain".
...	Arguments passed to sphere if the domain is not otherwise specified.
check	Logical. Check that points actually are inside the provided domain.

Value

Object of class "spp".

Examples

dom <- sphere(coord_type = "polar")
lat <- pi * c(1/4, 1/2, 3/4)
long <- 2 * pi * c(1/4, 1/2, 3/4)
X <- spp(lat, long, domain = dom)
X <- spp(lat, long, coord_type = "polar")

lat <- c(45, 0, -45)
long <- c(90, 180, -90)
X <- spp(lat, long)
dom <- sphere(coord_type = "geo_deg")
X <- spp(lat, long, domain = dom)
