Convenience Tools for Working with Airport Data.

airportr

This package uses open source airport data to provide tools to look up information, translate names and codes into other formats, as well as some basic calculation functions for measuring distances.

Installation

install.packages("airportr")
library(airportr)

Alternatively, the dev version can be installed from Github using devtools.

# install.packages("devtools")
devtools::install_github("dshkol/airportr")
library(airportr)

Example Usage: Lookup functions

This package is primarily to facilitate working with and translating structured airport data from one format into another.

# Return an airport name given an IATA code
airport_lookup("YVR", input_type = "IATA", output_type = "name")
[1] "Vancouver International Airport"

# Return an airport IATA code given an airport name
airport_lookup("Vancouver International Airport", input_type = "name", output_type ="IATA")
[1] "YVR"

# If input type is not specified will try to guess
airport_lookup("YVR", output_type = "city")
[1] "Vancouver"

# Return all available details for an aiport given an airport name, IATA code, or ICAO code
airport_detail("YVR")
# A tibble: 1 x 14

Example Usage: Distance functions

This package also includes some convenience functions for working with distances between airports.

# Calculate distance between two airports in km
airport_distance("YVR","LHR")
[1] 7580.963

Another common airport-related task is to locate airports in the vicinity of a city or specified location. This is easy to implement with the airports_near_airport() and airports_around() functions:

#' airports_near_airport("YEG")
# A tibble: 3 x 14
