this function produces a plot for displaying relative proportions of pairwise subgroup overlap, where the relative proportion is defined by |intersect(A, B)|/|A|, for any sets A and B and A is the baseline set. The letters represent subgroups defined by the categories of the selected covariates. Subgroup letters located around the two circles are considered as baselines; each has unidirectional arrowed lines to the other. In addition, there are two modes of display - one is that arrowed lines have different colours, reflecting the level of overlap proportions; the other is that lines have five thickness and types, indicating five levels of overlap proportions.

`font.size` |
