GridTopology-class {sp}R Documentation

Class "GridTopology" ~~~

Description

class for defining a rectangular grid of arbitrary dimension

Objects from the Class

Objects are created by using e.g.

GridTopology(c(0,0), c(1,1), c(5,5))

see SpatialGrid

Slots

cellcentre.offset:
numeric; vector with the smallest coordinates for each dimension; coordinates refer to the cell centre
cellsize:
numeric; vector with the cell size in each dimension
cells.dim:
integer; vector with number of cells in each dimension
bbox:
Object of class "matrix"; bounding box
proj4string:
Object of class "CRS"; projection

Extends

Methods

coordinates
signature(x = "SpatialGrid"): calculates coordinates for each point on the grid
coerce
signature(from = "GridTopology", to = "data.frame"): convert to data.frame with columns cellcentre.offset, cellsize and cells.dim
