spatial.to.ppp: Convert SpatialPoints and boundary polygon to spatstat ppp...

In inlabru: Bayesian Latent Gaussian Modelling using INLA and Extensions

Convert SpatialPoints and boundary polygon to spatstat ppp object

Description

Spatstat point pattern objects consist of points and an observation windows. This function uses a SpatialPoints object and a SpatialPolygon object to generate the points and the window. Lastly, the ppp() function is called to create the ppp object.

Usage

spatial.to.ppp(points, samplers)

Arguments

points	A SpatialPoints[DataFrame] object describing the point pattern.
samplers	A SpatialPolygons[DataFrame] object describing the observation window.

Value

A spatstat spatstat ppp object

Examples

if (require("spatstat.geom") &&
  bru_safe_sp() &&
  require("sp") &&
  require("terra", quietly = TRUE) &&
  require("sf", quietly = TRUE)) {
  # Load Gorilla data

  gorillas <- gorillas_sp()

  # Use nest locations and survey boundary to create a spatstat ppp object

  gp <- spatial.to.ppp(gorillas$nests, gorillas$boundary)
  class(gp)

  # Plot it

  plot(gp)
}
