Arguments

x	Vector of longitudinal angles (should range from 0 to 2*pi) or cartesian x coordinates of the data points.
y	Vector of latitudinal angles (should range from 0 to pi) or cartesian y coordinates of the data points.
z	Vector of cartesian z coordinates. Should be specified only if x and y represent cartesian coordiantes.
window	Window of observation, an object of class sphwin.
