Determine the KDE of occurrence coordinates and convert to polygon at density threshold

Description

Calculate the kernel density estimate (KDE) of input coordinates. Convert to an sf polygon at a specified density threshold.

Usage

coordsToKDEPolygon(coords, percentile = 50, proj4string, extent = 1)

Arguments

coords	Two-column data.frame, matrix, or SpatialPoints object containing longitude and latitude
percentile	Numeric density threshold percentile at which to draw output polygon
proj4string	Character string containing CRS information for coords.
extent	Controls the extent of the grid for estimating KDE.

Value

An sf polygon object of specified proj4string
