raw_variogram_metrics: Variogram parameters

In spatialwarnings: Spatial Early Warning Signals of Ecosystem Degradation

Variogram parameters

Description

Compute the nugget, partial sill, correlation range and structural variance on a matrix.

Usage

raw_variogram_metrics(
  mat,
  model = "sph",
  nmax = 100000L,
  nbins = 32,
  cutoff = NULL
)

Arguments

mat	A matrix
model	The variogram model to use, either "sph" (for a spherical model) or "exp" (for an exponential model)
nmax	The maximum number of pairs of cells to use when computing the variogram
nbins	Number of distance bins to use to compute the variogram
cutoff	Maximum distance to consider in the variogram. If NULL, then a distance equal to one third of the diagonal of the matrix is used
