gsDesign2 1.2.0

New features

• Harm boundaries are now supported in gs_design_ahr(), gs_power_ahr(), gs_design_npe(), and gs_power_npe() through the new harm, hpar, and test_harm arguments. Harm boundaries are available for group sequential designs with futility testing and are not supported for fixed designs (#640, thanks to @LittleBeannie, @yihui, and @keaven).
• Harm boundaries are now included in summary(), gs_bound_summary(), as_gt(), and as_rtf() output, with controls for custom labels and bound display (#640, thanks to @LittleBeannie, @jdblischak, @yihui, and @keaven).

Documentation

• A new vignette demonstrates how gs_design_ahr() reproduces gsDesign::gsSurv(method = "Schoenfeld") boundaries across test types, including designs with harm boundaries (#640, thanks to @LittleBeannie, @yihui, and @keaven).
