\title{Plotting Raster Images}
\usage{
\method{plot}{raster}(x, y,
     xlim = c(0, ncol(x)), ylim = c(0, nrow(x)),
     xaxs = "i", yaxs = "i",
     asp = 1, add = FALSE, \dots)
}
\alias{plot.raster}
\arguments{
  \item{x, y}{raster. \code{y} will be ignored.}
  \item{xlim, ylim}{Limits on the plot region (default from dimensions
    of the raster).}
  \item{xaxs, yaxs}{Axis interval calculation style (default means that
    raster fills plot region).}
  \item{asp}{Aspect ratio (default retains aspect ratio of the raster).}
  \item{add}{Logical indicating whether to simply add raster to an
    existing plot.}
  \item{\dots}{Further arguments to the \code{\link{rasterImage}} function.}
}
\description{
  This functions implements a \code{\link{plot}} method for raster images.
