GridTopology-class: 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 centroid 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

Methods

coordinates

signature(x = "SpatialGrid"): calculates coordinates for each point on the grid

summary

signature(object = "SpatialGrid"): summarize object

coerce

signature(from = "GridTopology", to = "data.frame"): convert to data.frame with columns cellcentre.offset, cellsize and cells.dim
