\usage{
\method{print}{pp3}(x, ...)
\method{print}{summary.pp3}(x, ...)
\method{summary}{pp3}(object, ...)
\method{unitname}{pp3}(x)
\method{unitname}{pp3}(x) <- value
}
\arguments{
\item{x,object}{
Object of class \code{"pp3"}.
}
\item{\dots}{
Ignored.
}
\item{value}{
Name of the unit of length. See \code{\link{unitname}}.
}
}
\details{
These are methods for the generic functions
\code{\link{print}}, \code{\link{summary}},
\code{\link{unitname}} and \code{\link{unitname<-}}
for the class \code{"pp3"} of three-dimensional point patterns.
The \code{print} and \code{summary} methods print a description
of the point pattern.
The \code{unitname} method extracts the name of the unit of
length in which the point coordinates are expressed.
The \code{unitname<-} method assigns the name of the unit of length.
}
\value{
For \code{print.pp3} the value is \code{NULL}.
For \code{unitname.pp3} an object of class \code{"units"}.
