Kfn {spatial}R Documentation

Compute K-fn of a Point Pattern

Description

Actually computes L = sqrt(K/pi).

Usage

Kfn(pp, fs, k=100)

Arguments

pp a list such as a pp object, including components x and y
fs full scale of the plot
k number of regularly spaced distances in (0, fs)

Details

relies on the domain D having been set by ppinit or ppregion.

Value

A list with components

x vector of distances
y vector of L-fn values
k number of distances returned – may be less than k if fs is too large
dmin minimum distance between pair of points
lm maximum deviation from L(t) = t

Examples

towns <- ppinit("towns.dat")
par(pty="s")
plot(Kfn(towns, 10), type="s", xlab="distance", ylab="L(t)")
