\title{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{
\item{Q}{A quadrature scheme (an object of class \code{"quad"}).}
}
\value{
A point pattern (of class \code{"ppp"}).
}
\details{
The argument \code{Q} should be a quadrature scheme (an object of class
\code{"quad"}, see \code{\link{quad.object}} for details).
This function combines the data and dummy points of \code{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 \code{\link{as.ppp}} will perform the same task.

\examples{
data(simdat)
Q <- quadscheme(simdat, default.dummy(simdat))
U <- union.quad(Q)
\dontrun{plot(U)}
# equivalent:
U <- as.ppp(Q)
