randGrid: Random drawing of a Grid object

Description

Random drawing of a Grid object

Usage

randGrid(dim = 1L + rpois(1L, lambda = 3), nxMin = 1L, nxE = 4L, nlevels,
  dimNames)

Arguments

dim

The spatial dimension.

nxMin

Minimum number of nodes. Integer vector of length 1 or dim.example(Grid).

nxE

Expected number of nodes. Numeric vector of length 1 or dim.

nlevels

Integer vector giving the number of levels for each spatial dimension.

dimNames

Names of the spatial dimensions.

Value

• An object with S4 class "Grid".

Details

The nodes are drawn by first choosing their number for each spatial dimension using a Poisson distribution, and then by drawing a sample of the uniform distribution with the suitable size.

Examples

set.seed(1234)
## specify dim: number of levels are random!
GD <- randGrid(dim = 4)
plot(GD)
## specify number of levels (hence dim)
GD2 <- randGrid(nlevels = c(2, 3, 4))
plot(GD2)
