Kest_directional_old: Directed K function, old and slow

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

Directed K function, old and slow

Description

We use translation edge correction.

Usage

Kest_directional_old(x, u, epsilon, r, pregraph)

Arguments

x	pp, list with $x~coordinates $bbox~bounding box
u	unit vector of direction
epsilon	Central angle for the directed cone (total angle is 2 epsilon)
r	radius vector at which to evaluate K
pregraph	A super graph for determining neighbourhoods

Details

Compute the sector K function.

Try Kest_anin for a bit better version that does also second order inhomogeneous patterns.

Value

Returns a dataframe.
