SpatialGrid-class {sp} | R Documentation

## Class "SpatialGrid" ~~~

### Description

class for defining a full, rectangular grid of arbitrary dimension

### Objects from the Class

Objects are created by using e.g.

SpatialGrid(grid)

with grid of class GridTopology-class

### Slots

`grid`
  object of class GridTopology-class, defining the grid topology (offset, cellsize, dim)
`grid.index`
  index of points in full grid, or integer(0)
`coords`
  coordinates of points, or bbox of grid
`bbox`:
  Object of class `"matrix"`; bounding box
`proj4string`:
  Object of class `"CRS"`; projection

### Extends

Class `"SpatialPoints"` directly; Class `"Spatial"`, by class `"SpatialPoints"`.

### Methods

coordinates
  `signature(x = "SpatialGrid")`: calculates coordinates for each point on the grid; coordinates are not stored in objects of class SpatialGrid
summary
  `signature(x = "SpatialGrid")`: gives summary
plot
  `signature(x = "SpatialGrid")`: plots cell centers
"["
  `signature(x = "SpatialGrid")`: select rows and columns

    summary(x)
    coordinates(x)
    y = SpatialGrid(grid = x)
    class(y)
