dot-find_dists: Calculate (signed) distances between coordinates

In mcgf: Markov Chain Gaussian Fields Simulation and Parameter Estimation

Calculate (signed) distances between coordinates

Description

Calculate (signed) distances between coordinates

Usage

.find_dists(
  grid,
  names = NULL,
  longlat = TRUE,
  origin = 1L,
  return_grid = FALSE,
  lon_ref,
  lat_ref
)

Arguments

grid	A matrix of 2D points, first column x/longitude, second column y/latitude.
names	Names of locations.
longlat	Logical, if TURE Great Circle (WGS84 ellipsoid) distance; if FALSE, Euclidean distance.
origin	Optional; used when longlat is TRUE. An integer index indicating the reference location which will be used as the origin.
return_grid	Logical; used when longlat is TRUE. If TRUE the mapped coordinates on a 2D plane is returned.
lon_ref	Reference longitude when computing the longitudinal distances. Default is the mean of longitudes in grid.
lat_ref	Reference latitude when computing the latitudinal distances. Default is the mean of latitudes in grid.

Value

List of signed distances.
