class for defining a rectangular grid of arbitrary dimension

Objects are created by using e.g.

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

see SpatialGrid

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

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

signature(x = "SpatialGrid")

signature(object = "SpatialGrid"): summarize object

signature(object = "SpatialGrid")

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

signature(from = "GridTopology", to = "data.frame")
