TT.mahalanobis: Calculates the Mahalanobis distance between clay silt and sand.

Description

Function that calculated the Mahalanobis distance between clay silt and sand, on a regular x-y grid (back-transformed to Clay silt and sand for Mahalanobis calculation). The underlying function is mahalanobis() by R Development Core Team (2009)

Usage

TT.mahalanobis(
  geo,
  tri.data,
  css.names = NULL,
  text.tol = NULL,
  text.sum = NULL,
  blr.clock = NULL,
  tri.sum.tst = NULL,
  tri.pos.tst = NULL,
  set.par = FALSE,
  n = 25,
  center = NULL,
  cov.mat = NULL,
  inverted = FALSE,
  ...,
  alr = FALSE,
  divisorvar = 2
)

Arguments

geo: See TT.plot
tri.data: See TT.plot
css.names: See TT.plot
text.tol: See TT.plot
text.sum: See TT.plot
blr.clock: See TT.plot
tri.sum.tst: See TT.plot
tri.pos.tst: See TT.plot
set.par: If TRUE parameters are set automatically to their defualt value
n: Number of points in the grid.
center: Passed to mahalanobis
cov.mat: Passed to mahalanobis
inverted: Passed to mahalanobis
...: More argument passed to mahalanobis
alr: If TRUE an additive log-ratio transformation of the data is performed, and the Mahalanobis distance is computed on all classes but css.names[divisorvar]
divisorvar: The Mahalanobis distance will be computed on all the texture class but css.names[divisorvar]
