union.quad: 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").

Value

• A point pattern (of class "ppp").

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.
