  timename = "Month",
  alpha = NULL
)

digits	Number of digits past the decimal to be printed in the body of the table.
ddigits	Number of digits past the decimal to be printed for the natural parameter delta.
tdigits	Number of digits past the decimal point to be shown for estimated timing of each analysis.

Examples

library(gsDesign2)

x <- gs_design_ahr(info_frac = c(.25, .75, 1), analysis_time = c(12, 25, 36))
gs_bound_summary(x)

x <- gs_design_wlr(info_frac = c(.25, .75, 1), analysis_time = c(12, 25, 36))
gs_bound_summary(x)

# Report multiple efficacy bounds (only supported for AHR designs)
x <- gs_design_ahr(analysis_time = 1:3*12, alpha = 0.0125)
gs_bound_summary(x, alpha = c(0.025, 0.05))
