In order to simplify code, most terrainr
functions expect a set S4
class representation of coordinate pairs and bounding boxes. If the provided
data isn't in the expected S4 format, these functions are used to cast the
data into the target class.
terrainr_coordinate_pair(coords, coord_units = c("degrees", "radians"))
terrainr_coordinate_pair
object
A vector of length 2 containing a latitude and longitude. If unnamed, coordinates are assumed to be in (latitude, longitude) format; if named, the function will attempt to figure out which value represents which coordinate. Currently this function understands "lat", "latitude", and "y" as names for latitude and "lng", "long", "longitude", and "x" for longitude.
String indicating whether coordinates are in degrees or radians. Degrees stored in radians will be converted to degrees.
