Circular Correlation Wheel Plots // Draws circular "correlation wheel" plots in R, straight from a data frame of one row per observation. Variables are arranged around a circle, grouped and colour-tiled by category, and connected by curved links whose colour maps to the correlation coefficient, computed via a thin wrapper around corr.test() from the 'psych' package. Non-significant, weak, and within-category correlations can be masked. Categories, colours, and labels are all user- configurable.
