polygonise: Convert the Dirichlet tessellation to polygons and clip if so...

In skiptoniam/qrbp: Quasirandom quardature scheme using dirichlet tesselation for spatial Poisson point process models

Convert the Dirichlet tessellation to polygons and clip if so desired.

Description

Convert the Dirichlet tessellation to polygons and clip if so desired.

Usage

polygonise(
  x,
  window = NULL,
  clippy = TRUE,
  crs = sf::st_crs("EPSG:4326"),
  unit,
  ...
)

Arguments

x	Dirichlet tessellation object
window	polygon A polygon to clip the dirichlet tessellation - intersection between boundary polygons and polygon
clippy	Logical Clip to the bounding box or polgon if polyclip = TRUE.
crs	CRS Projection of coordinates default is "EPSG:4326" (lon/lat wgs84)
unit	Character The type of area to return. The default is "geo" and returns the area based on the euclidean distance between geographic coordinates. This will default to the values of the raster and presence coordinate system. Alternatively, meters squared "m", kilometers squared "km", or hectares "ha" can be used.
\dots	Additional arguments for a polygonise function

Examples

library(sf)
coords <- matrix(runif(2000),ncol=2)
tess <- dirTess(coords)
tess.polys <- polygonise(tess)
plot(st_geometry(tess.polys$polygons), col=hcl.colors(100))
points(coords,col='tomato',pch=16, cex=.3)
