maraca: The Maraca Plot: Visualization of Hierarchical Composite Endpoints in Clinical Trials

Library that supports visual interpretation of hierarchical composite endpoints (HCEs). HCEs are complex constructs used as primary endpoints in clinical trials, combining outcomes of different types into ordinal endpoints, in which each patient contributes the most clinically important event (one and only one) to the analysis.
