gsDesign2 1.1.3

Bug fixes

• Fix the bug of gs_design_rd() when info_scale = "h0_h1_info" (#402, thanks to @LittleBeannie).
• Fix the bug of gs_spending_combo() to enable HSD spending function (#444, thanks to @LittleBeannie).
• Fix the bug of fixed_design_maxcombo() regarding the upper bounds (#445, thanks to @elong0527).
• Fix the bug of gs_design_wlr() when the design is driven by information fraction only (#446, thanks to @LittleBeannie).
• Fix the bug of pw_info() when there are many piecewise HRs (#460, thanks to @LittleBeannie).

Statistical improvements

• The gs_update_ahr() function (test version) is updated to

  • Enable unchanged futility bounds when it is fixed at the original design (#408, thanks to @LittleBeannie).
  • Allow boundary updates when only certain interim analysis data is available (#436, thanks to @LittleBeannie).
  • Allow boundary updates when alpha changes by keeping the same info_scale as the original design (#470, @LittleBeannie).

• Rounding of integer design is updated (#488, #484, #486, thanks to @LittleBeannie).

• Integer design (i.e., integer sample size and events) is updated to ensure exact integer sample size and events (#452, #460, thanks to @LittleBeannie and @yihui).

• Change the information fraction displayed at the summary-gt table from under H1 to H0 for logrank tests (#439, thanks to @LittleBeannie).

• Add the sample size as the output of ahr() and pw_info() (#427, #433, thanks to @LittleBeannie).

User interface improvements

• Enable passing named vector of col_decimals and analysis_decimals to summary.gs_design() (#403, #431, @jdblischak).

Coding practice improvements

• Add robust check if lower is equivalent to gs_b (#413, thanks to @jdblischak )
• The summary(), as_gt() as_rtf(), and to_integer() functions are refactored (#448, #449, #450, #465, #461, thanks to @yihui).
• Remove the full_alpha argument from as_rtf.gs_design() (#458, thanks to @yihui).
• Other coding practice improvement worth mentioning (#409, #412, #429, #437, #440, #447, #453, #464, #467, $475, thanks to @yihui, @nanxstats, and @jdblischak).

Documentation

• Update the documentation of gs_b() (#415, @jdblischak)

Testing

• More developer tests of gs_power_ahr() are added (#420, @LittleBeannie).
• More developer tests of summary() are added (#422, #426, thanks to @yuliasidi, @jdblischak and @LittleBeannie).
• Independent tests of ahr_blinded() are added (#435, thanks to @DMuriuki).
• More developer tests of to_integer() are added (#476, thanks to @LittleBeannie).
