SpatialPixels-class {sp} | R Documentation

## Class "SpatialPixels" ~~~

### Description

class for defining a pixels, forming a possibly incomplete rectangular grid of arbitrary dimension

### Objects from the Class

Objects are created by using e.g.

SpatialPixels(points)

with points of class SpatialPoints-class

### Slots

`grid`
  object of class GridTopology-class, defining the grid topology (offset, cellsize, dim)
`grid.index`
  integer; index of points in full grid
`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 = "SpatialPixels")`: calculates coordinates for each point on the grid; coordinates are not stored in objects of class SpatialGrid
summary
  `signature(x = "SpatialPixels")`: gives summary
plot
  `signature(x = "SpatialPixels")`: plots cell centers
"["
  `signature(x = "SpatialPixels")`: select pixel cells

### Examples

    data(meuse.grid)
    pts = meuse.grid[c("x", "y")]
    y = SpatialPixels(SpatialPoints(pts))
    class(y)
    y
    summary(y)
    plot(y)
