Kcir: K-function of a three-dimensional point pattern

In adchSTATS/spatstatciradd: Additions to spatstat

Description

Estimates the K-function from a point pattern on the circle

Usage

Kcir(X, r = NULL, rmax = NULL, nrval = 128, intenss = NULL, ...)

Arguments

X	Circular point pattern (object of class ppc).
r	Optional. Vector of values for the argument r at which K(r) should be evaluated. Users are advised not to specify this argument; there is a sensible default. If necessary, specify rmax.
rmax	Optional. Maximum desired value of the argument r.
nrval	Optional. Number of values of r for which K3(r) will be estimated. A large value of nrval is required to avoid discretisation effects.
intenss	Optional. Required for computing the inhomogeneous K function. Either NULL, a numeric vector or a numerix matrix. If NULL the homogeneous K function is computed. If a numeric vector then it should contain estimated intensities at the observed locations. If a matrix then it should contain the product of every pair of estimated intensities.
...	Ignored.

Details

No edge correction have been implemented. And it is assumede that the data are observed on the entire circle, i.e. the window is the entire circle.

Value

A function value table (object of class fv) that can be plotted, printed or coerced to a data frame containing the function values.
