Gsector: Directional Nearest neighbour distribution(old)

In antiphon/Kdirectional: Analysis of anisotropy in point patterns using second order statistics

Directional Nearest neighbour distribution(old)

Description

Estimate the directional nearest neighbour CDF.

Usage

Gsector(x, r, theta, unit, directions, epsilon, n_dir = 10)

Arguments

x	point pattern, $x coords $bbox bounding box
r	Ranges
theta	Direction sector central angles, list of ncol(x$x)-components.
unit	Alternative to theta, a matrix of direction vectors.
directions	alternative to theta, unit vectors
epsilon	Direction sector width angles
n_dir	If theta not given, greate a grid with this resolution.

Details

This is a directed sector version of the G-function in spatstat.

Directions are angle to positive x-axis (2D) or azimuth, inclination (3D). Theta should be a list of length 1 (2D) and 2 (3D) defining a grid of these angles.
