Convert SpatialPoints and boundary polygon to spatstat ppp object
Source:R/spatstat.R
spatial.to.ppp.Rd
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.
Arguments
- points
A
SpatialPoints[DataFrame]
object describing the point pattern.- samplers
A
SpatialPolygons[DataFrame]
object describing the observation window.
Examples
# \donttest{
if (require("spatstat.geom")) {
# Load Gorilla data
data("gorillas", package = "inlabru")
# 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)
}
