In celestial: Collection of Common Astronomical Conversion Routines and Functions

Description

Transforms 3D spherical coordinates to cartesian coordinates. The user can choose to input the spherical coordinates in degrees or radians.

Usage

sph2car(long, lat, radius = 1, deg = TRUE)

Arguments

long	Longitude values, can also contain a matrix of long, lat and radius (in that order).
lat	Latitude values.
radius	Radius values.
deg	Specifies if input is in degrees (default) or radians.

Details

This is a low level function that is used for plot transformations.

Value

A data.frame is returned containing the columns x, y and z.
