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
