Methods for Point Patterns on a Linear Network
}
\description{
These are methods specifically for the class \code{"lpp"} of point patterns on
linear networks.
}
\usage{
\method{as.ppp}{lpp}(X, ..., fatal=TRUE)
\method{as.psp}{lpp}(x, ..., fatal=TRUE)
\method{marks}{lpp}(x, ...) <- value
\method{nsegments}{lpp}(x)
\method{print}{lpp}(x, ...)
\method{print}{summary.lpp}(x, ...)
\method{summary}{lpp}(object, ...)
\method{unitname}{lpp}(x)
\method{unitname}{lpp}(x) <- value
\method{unmark}{lpp}(X)
}
\arguments{
\item{x,X,object}{
An object of class \code{"lpp"} representing a point pattern
on a linear network.
}
\item{\dots}{
Arguments passed to other methods.
}
\item{value}{
Replacement value for the \code{marks} or \code{unitname}
of \code{x}. See Details.
}
\item{fatal}{
Logical value indicating whether data in the wrong format
should lead to an error (\code{fatal=TRUE}) or a warning
(\code{fatal=FALSE}).
}
}
\details{
These are methods for the generic functions
\code{\link[spatstat.geom]{as.ppp}},
\code{\link[spatstat.geom]{as.psp}},
\code{\link[spatstat.geom]{marks<-}},
\code{\link[spatstat.geom]{nsegments}},
\code{\link[base]{print}},
\code{\link[base]{summary}},
\code{\link[spatstat.geom]{unitname}},
\code{\link[spatstat.geom]{unitname<-}} and
\code{\link[spatstat.geom]{unmark}}
for objects of the class \code{"lpp"}.
For \code{"marks<-.lpp"} the replacement \code{value}
should be either \code{NULL}, or a vector of length equal
to the number of points in \code{x},
or a data frame with one row for each point in \code{x}.
For \code{"unitname<-.lpp"} the replacement \code{value}
should be a valid name for the unit of length, as
described in \code{\link[spatstat.geom]{unitname}}.
}
\section{Other methods}{
An object of class \code{"lpp"} also inherits the class
\code{"ppx"} for which many other methods are available.
See \code{\link[spatstat.geom:methods.ppx]{methods.ppx}}.
}
\value{
See the documentation on the corresponding generic function.
