In drodriguezperez/whereiam: whereiam: Geolocation package and spherical trigonometry calculations

whereiam

whereiam is a geolocation package for R.

Installation

You can install whereiam from github using the devtools package

require(devtools)
install_github('whereiam', 'drodriguezperez')

Features

whereiam allow to access to IP based geolocation services from R. The package also includes access to different services of geocoding and reverse geocoding.

The coordinates can be stored in objects that allows performing calculations such as distance, the half-way point or the bearing of two points.

Geocoding examples

The external IP can be obtained using

ip = getExternalIP()

The function returns a string with the IP address, if there is no IP address, for example by not being connected to the Internet, will return NULL. From the IP address it can be obtained geographical location information using:

cord <- getIpCoordinates(ip)

Finally it is possible to get the address by using the geographic coordinates using reverse geocoding services with the function:

info <- reverseGeocoding(cord$latitude, cord$longitude)

Calculation examples

It is possible to create new geographic points through introduce the latitude and longitude in the method Coordinate:

posc <- Coordinate(42.8806027, -8.5445684)

and calculate different values

• Distance in km: haversineDistance(cord, posc)
• Half-way poin: midpoint(cord, posc)
• Bearing: bearing(cord, posc)
