These functions generate random points on a sphere using different rules.

1 2 | ```
runifsphere(n)
runifsphere.wrong(n)

`n` |
The number of points to be simulated. |

`runifsphere`

generates uniformly-distributed random points on the
sphere.

`runifsphere.wrong`

generates random points which are uniformly
distributed in (longitude, latitude) coordinates.
These are not uniformly distributed on the sphere.

A data frame containing two columns of coordinates: the first column for longitude, the second column for latitude.
