Circular Summary Statistics
Computes circular summary statistics including the sample size, mean direction and mean resultant length and quartiles.

Each observation is treated as a unit vector or a point on the unit circle. The resultant vector of the observations is found, and the direction of the resultant vector is returned as well as its length divided by the sample size.
Returns a vector with the sample size, the sample mean direction and the sample mean resultant length.
