Grouped Boxplots for Circular Data

Plotting functions to create circular boxplots for grouped data. The primary 2-dimensional version creates concentric circular boxplots for specified groups, scaling the width of each boxplot to adjust for human perception. The 3-dimensional version maps these plots onto a torus which is suitable for periodic circular data such as wind direction over the course of a year. An example dataset of this type is provided for reference. For examples of circular boxplots and additional implementation details, see Berlinski et al. (2026) .

CircularBoxplots

Overview

• The function CircularBoxplots::GroupedCircularBoxplot(x) creates a grouped circular boxplot from the list of circular vectors x.
• The function CircularBoxplots::GroupedCircularBoxplot.3D(x) creates a grouped circular boxplot around the 3D torus surface from the list of circular vectors x.
