randGrid: Random drawing of a 'Grid' object

In IRSN/smint: Smooth Multivariate Interpolation for Gridded and Scattered Data

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.

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.

Value

An object with S4 class "Grid".

Note

This function is not not for drawing random design points from within the object.

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)
