ganiso_d: Anisotropic distance-related characteristics
In gear: Geostatistical Analysis in R

Description Usage Arguments Value Examples

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.

1	ganiso_d(coords1, coords2, radians = TRUE, invert = TRUE)

`coords1`	An N \times 2 matrix of spatial coordinates.
`coords2`	An M \times 2 matrix of spatial coordinates. Is missing, then `coords2 = coords1`.
`radians`	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.
`invert`	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.
