Computes necessary distance-related characteristics when
there is geometric anisotropy. This is essentially an
internal function to evaluate a
cmodStd object produced by cmod_std
when the anisotropy ratio differs from 1.
ganiso_d(coords1, coords2, radians = TRUE, invert = TRUE)An \(N \times 2\) matrix of spatial coordinates.
An \(M \times 2\) matrix of spatial
coordinates. Is missing, then coords2 = coords1.
A logical value indicating whether the
angles returned should be in degrees or radians. The
default is FALSE, indicating that the returned
angles are in degrees.
A logical value indicating whether the axes
of the coordinates should be inverted (i.e., the x- and
y-axis are switched). The default is TRUE to
mimic results from other geostatistical R packages like
gstat, geoR, and other software like
GSLIB and GeoEAS. Set to FALSE to
use the typical x- and y-axes.
A ganisoD object with components d
and angles, which is the distance matrix between
the coordinates and the angles between the coordinates.
The angles are returned in radians.
