\title{Class "SpatialGrid" }
\description{ class for defining a full, rectangular grid of
arbitrary dimension }
\section{Objects from the Class}{
Objects are created by using e.g.
SpatialGrid(grid)
with grid of class \link{GridTopology-class}
}
\section{Slots}{
\describe{
\item{\code{grid}}{ object of class \link{GridTopology-class}, defining the
grid topology (offset, cellsize, dim) }
\item{\code{bbox}:}{Object of class \code{"matrix"}; bounding box }
\item{\code{proj4string}:}{Object of class \code{"CRS"}; projection }
}
}
\section{Extends}{
Class \code{"SpatialPoints"} directly;
Class \code{"Spatial"}, by class \code{"SpatialPoints"}.
}
\section{Methods}{
\describe{
\item{coordinates}{\code{signature(x = "SpatialGrid")}: calculates coordinates for
each point on the grid; coordinates are not stored in objects of class SpatialGrid}
\item{summary}{\code{signature(object = "SpatialGrid")}: summarize object}
\item{plot}{\code{signature(x = "SpatialGrid")}: plots cell centers }
\item{"["}{\code{signature(x = "SpatialGrid")}: select rows and columns }
}
