get_distance: Distance between two geographic entities

In julianhinz/gravity.distances: Gravity-consistent distances between geographic entities

Description

This function allows you to get distances between two geographic entities.

Usage

get_distance(origin, destination, year = 2012, theta = -1,
  data = NULL, code_format = "iso3c", data_url = NULL,
  data_store = T)

Arguments

origin	Vector containing origin entities. (character)
destination	Vector containing destination entities. (character)
year	Vector containing years between 1992 and 2012, defaults to 2012 (numeric)
theta	Vector containing theta value between -1 and 1, defaults to -1 for the harmonic mean. Set to 0 for geometric mean, 1 for arithmetic mean. (numeric)
data	Data.table with computed distances, defaults to gravity.distances::distances_data
code_format	Character string indicating format of origin and destination corresponding to the countrycode package. Defaults to "iso3c".
data_url	Character string indicating url from which data should be downloaded.
data_store	Logical indicator whether downloaded data should be stored permanently.

Examples

get_distance("DEU", "CAN")
