Transform a 3D vector constituting a cartesian coordinate set to spherical coordinates

1	car2sph(X, deg = FALSE, rep = "sph", unitlength = TRUE)

`X`	A numerical vector or matrix whos entries constitute a cartesian coordinate. A vector should have 3 entries and a matrix should have 3 columns.
`deg`	Logical value indicating whether the output should be in randians or degrees. Radian is default.
`rep`	Determine the representation of the spherical coordinates. If `"sph"` long will range from `0` to `2 * pi` and lat will range from `0` to `pi`. The classical representation of spherical coordinates in radians. If `"geo"` long will range from `-pi` to `pi` and lat will range from `0` to `pi`. The geografical representation in radians. Deafult is "sph".
`unitlength`	Logical values indicating if the points should be returned with unit length. If TRUE (default) `r` will be set to 1.
