Directional statistics package for Julia. Currently includes several circular and spatial descriptive statistics, see reference below for details.

Package contains submodules, and many functions are indended to be qualified on call. This lets us use names such as mean() and still have no conflicts with functions in Statistics or StatsBase.

using DirectionalStatistics

Circular.mean(...)

All circular statistics operate in a 2π range by default, that corresponds to the natural range of angles. Arbitrary ranges are supported and can be specified as an interval:

using IntervalSets

Circular.mean(array, 0..π)
Circular.mean(array, -180..+180)
