These functions generate random points on a
sphere using different rules.
Usage
runifsphere(n)
runifsphere.wrong(n)
Arguments
n
The number of points to be simulated.
Value
A data frame containing two columns of coordinates: the first column
for longitude, the second column for latitude.
Details
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.
