R: Union of Data and Dummy Points

union.quad {spatstat} | R Documentation

## Union of Data and Dummy Points

### Description

Combines the data and dummy points of a quadrature scheme into a single point pattern.

### Usage

     union.quad(Q)

### Arguments

`Q` | A quadrature scheme (an object of class `"quad"`).

### Details

The argument `Q` should be a quadrature scheme (an object of class `"quad"`, see `quad.object` for details).

This function combines the data and dummy points of `Q` into a single point pattern. If either the data or the dummy points are marked, the result is a marked point pattern.

The function `as.ppp` will perform the same task.

### Value

A point pattern (of class `"ppp"`).
