Random drawing of a Grid object

1 2	randGrid(dim = 1L + rpois(1L, lambda = 3), nxMin = 1L, nxE = 4L, nlevels, dimNames)

`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.

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.

An object with S4 class "Grid".

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

Grid-class.

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)
