SpatialGrid-class function

Class "SpatialGrid"

class for defining a full, rectangular grid of arbitrary dimension class

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)
• 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(object = "SpatialGrid"): summarize object
• plot: signature(x = "SpatialGrid"): plots cell centers
• "[": signature(x = "SpatialGrid"): select rows and columns
