iso_spatial_floor: Isotropic spatial simulation wrapper

In SpatialFloor: Spatial Floor Simulation (Isotropic)

Description

This function load grid floor and generate the simulated floor

Usage

iso_spatial_floor(D, cov.var = "exp", nugget = 0, sill, ranges, mu = 0)

Arguments

D	The distance matrix
cov.var	the var-cov function of producing var-cov matrix. 'exp' is exponential, 'gau' is Gaussian
nugget	the nugget value of the var-cov function
sill	the sill(variance, sigma^2) of the var-cov function
ranges	the range value of var-cov function
mu	the mean value of the simulated spatial floor

Value

A vector with the same length of grid floor

Examples

D = spatial_dist(expand.grid(1:5, 1:5))
iso_spatial_floor(D, sill=50, ranges=2)
