In jvieroe/dyadicdist: Compute Dyadic Distances

Description

This function calculates the geodesic distance between any dyads (pairs of points i and j) from datasets x and y and stores the result in a long tibble

Usage

ddist_xy(
  x = NULL,
  y = NULL,
  ids = NULL,
  coords_x = c("longitude", "latitude"),
  coords_y = c("longitude", "latitude"),
  crs = c(4326, 4326),
  crs_transform = FALSE,
  new_crs = NULL
)

Arguments

x	an object of class data.frame or tibble.
y	an object of class data.frame or tibble.
ids	variables uniquely identifying geospatial points in data x and y. Can be of type numeric, integer, character, or factor
coords_x	names of the numeric coordinate variables in data x. Defaults to c("longitude", "latitude")
coords_y	names of the numeric coordinate variables in data y. Defaults to c("longitude", "latitude")
crs	valid EPSG's for your coordinates in data x and y. Defaults to c(4326, 4326).
crs_transform	a logical value indicating whether to transform the CRS. Defaults to FALSE
new_crs	a valid EPSG for a new CRS. See rgdal::make_EPSG() or https://epsg.org/home.html

Value

a long tibble with dyads and dyadic distances incl. a distance unit indicator
