Plots a linear network

\usage{
\method{plot}{linnet}(x, ..., main=NULL, add=FALSE,
do.plot=TRUE,
show.vertices=FALSE, show.window=FALSE,
args.vertices=list(), args.segments=list())
}
\arguments{
\item{x}{
Linear network (object of class \code{"linnet"}).
}
\item{\dots}{
Graphics arguments passed to \code{\link[spatstat.geom]{plot.psp}}
and \code{\link[spatstat.geom]{plot.ppp}}.
}
\item{main}{
Main title for plot. Use \code{main=""} to suppress it.
}
\item{add}{
Logical. If \code{TRUE}, superimpose the graphics
over the current plot. If \code{FALSE}, generate a new plot.
}
\item{do.plot}{
Logical value specifying whether to actually perform the plot.
}
\item{show.vertices}{
Logical value specifying whether to plot the vertices as well.
}
\item{show.window}{
Logical value specifying whether to plot the window containing the
linear network.
}
\item{args.segments}{
Optional list of arguments passed to \code{\link[spatstat.geom]{plot.psp}}
when plotting the line segments of the network.
These arguments override any arguments in \code{\dots}.
}
\item{args.vertices}{
Optional list of arguments passed to \code{\link[spatstat.geom]{plot.ppp}}
when plotting the vertices of the network (only when \code{vertices=TRUE}).
These arguments override any arguments in \code{\dots}.
}
}
\details{
This is the plot method for class \code{"linnet"}.
The line segments of the network \code{x} are plotted
using \code{\link[spatstat.geom]{plot.psp}}.
If \code{show.vertices=TRUE}, the vertices of the network will also be
plotted, using \code{\link[spatstat.geom]{plot.ppp}}.
If \code{show.window=TRUE}, the window surrounding the network will also
be plotted.
If the vertices or line segments of \code{x} are marked,
the marks are not displayed by default. To plot the marks,
set \code{use.marks=TRUE}. To plot the marks and plot the associated legends,
set \code{use.marks=TRUE, legend=TRUE}. To plot only the marks of the
segments and not the marks of the vertices, set
\code{args.segments=list(use.marks=TRUE)} and so on.
}
\value{
An (invisible) list with two elements, \code{segments} and
\code{vertices} describing the representation of the marks.
The element \code{segments} contains
the result of \code{\link[spatstat.geom]{plot.psp}}
(either a \code{colourmap}, a numeric value or an \code{owin}).
The element \code{vertices} contains the result
of \code{\link[spatstat.geom]{plot.ppp}} (a \code{symbolmap})
or \code{NULL}.
The result also has attribute \code{"bbox"}
giving the bounding box for the plot.
