In Directional: A Collection of Functions for Directional Data Analysis

Column-wise uniformity tests for circular data

Description

Column-wise uniformity tests for circular data.

Usage

colwatsons(u, rads = FALSE)

Arguments

u	A numeric matrix containing the circular data which are expressed in radians. Each column is a different sample.
rads	A boolean variable. If the data are in radians, put this TRUE. If the data are expressed in degrees make this FALSE.
