circlecorR - 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.
