union.quad {spatstat.geom}

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").
