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)
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
