Description Usage Arguments Author(s) References See Also Examples

This function provides a plot that displays the frequencies, percentages, cumulative percentages or densities of the individual causal association (ICA; *R^2_{H}* or *R_{H}*), and/or the odds ratios for *S* and *T* (*θ_{S}* and *θ_{T}*).
