buff_voronoi: Function to generate buffers intersected by Voronoi polygons.

In RichDeto/EPP: Evaluation of Proximity Programs

Function to generate buffers intersected by Voronoi polygons.

Description

Generate buffers from points coordinates, according to a distance/s of radium, but intersect by Voronoi Polygons. The output of the function is a SpatialPolygonDataFrame with the id of the initial DataFrame.

Usage

buff_voronoi(x, id = "id", w_buff = 1000, crs = sp::CRS("+init=epsg:32721"))

Arguments

x	DataFrame with unless three variables: x, y, and id
id	Variable name (Character) to identify cases. Default = 'id'
w_buff	Buffer distance of radium in meters. Default = 1000
crs	Coordinate Reference Systems (CRS). Default = CRS("+init=epsg:32721")

Value

Return a SpatialPolygonDataFrame with the sames variables of the initial DataFrame#'
