R: Range of Interaction for a Determinantal Point Process Model

reach.dppm {spatstat.core} | R Documentation

## Range of Interaction for a Determinantal Point Process Model

### Description

Returns the range of interaction for a determinantal point process model.

### Usage

      ## S3 method for class 'dppm'
    reach(x, ...)

      ## S3 method for class 'detpointprocfamily'
    reach(x, ...)

### Arguments

`x` | Model of class `"detpointprocfamily"` or `"dppm"`.
`...` | Additional arguments passed to the range function of the given model.

### Details

The range of interaction for a determinantal point process model may defined as the smallest number R such that g(r)=1 for all r>=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. For example in the Matern model this defaults to finding R such that g(R)=0.99.

### Value
