GridTopology-class function

Class "GridTopology"

class for defining a rectangular grid of arbitrary dimension class

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
