rhumbDistance: Calculate distance between two points along a rhumb line

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

Description

The function calculates distances between the two points along a rhumb line. The rhumb lines are path of constant bearing and crosses all meridians at the same angle. The rhumb lines are generally longer than great-circle routes.

Usage

  rhumbDistance(...)

  ## Default S3 method:
 rhumbDistance(latitude1, longitude1,
    latitude2, longitude2, units = "km", ...)

  ## S3 method for class 'Coordinate'
 rhumbDistance(coordinate1,
    coordinate2, units = "km", ...)

Arguments

latitude1	the first latitude coordinate
longitude1	the first longitude coordinate
latitude2	the second latitude coordinate
longitude2	the second longitude coordinate
units	a string with the distance units (default kilometers)
coordinate1	the first coordinate class variable
coordinate2	the second coordinate class variable
...	other arguments

cord1    <- Coordinate(43, -8)
cord2    <- Coordinate(42, -7)
distance <- rhumbDistance(cord1, cord2)
