\title{Plot a Simulation Envelope}
\description{
Plot method for the class \code{"envelope"}.
}
\usage{
\method{plot}{envelope}(x, \dots, main)
}
\arguments{
\item{x}{
An object of class \code{"envelope"}, containing the variables to be plotted
or variables from which the plotting coordinates can be computed.
}
\item{main}{Main title for plot.}
\item{\dots}{
Extra arguments passed to \code{\link{plot.fv}}.
}
}
\value{
Either \code{NULL}, or a data frame giving the meaning of the
different line types and colours.
}
\details{
This is the \code{plot} method for the class \code{"envelope"}
of simulation envelopes. Objects of this class are
created by the command \code{\link{envelope}}.
This plot method is currently identical to \code{\link{plot.fv}}.
Its default behaviour is to shade the region
between the upper and lower envelopes in a light grey colour.
To suppress the shading and plot the upper and lower envelopes
as curves, set \code{shade=NULL}.
To change the colour of the shading, use the argument \code{shadecol}
which is passed to \code{\link{plot.fv}}.
See \code{\link{plot.fv}} for further information on how to
control the plot.
}
\examples{
E <- envelope(cells, Kest, nsim=19)
plot(E)
plot(E, sqrt(./pi) ~ r)
