Returns the range of interaction for a Cox or cluster point process model.

Usage
# S3 method for kppm
reach(x, …, epsilon)
Arguments
x

Fitted point process model of class "kppm".

epsilon

Optional numerical value. Differences smaller than epsilon are treated as zero.

Additional arguments passed to the range function of the given model.

Details

The range of interaction for a fitted point process model of class "kppm" may defined as the smallest number \(R\) such that \(g(r)=1\) for all \(r\ge R\), where \(g\) is the pair correlation function.

For many models the range is infinite, but one may instead use a value where the pair correlation function is sufficiently close to 1. The argument epsilon specifies the tolerance; there is a sensible default.
