All functions

absstopPlot()

Plot absolute stopping probs

convertRisks()

Convert the proportion of events in the intervention groups to risk differences and ratios and vice versa.

cumstopPlot()

Plot cumulative stopping probs

findbound()

Find stopping boundary via binomial exact tests

getAlphaPerTest()

getAlphaPerTest

getHarmBound()

Harm boundaries for safety testing

harmboundPlot()

Plot harmbounds and the observed events

opcharNPlot()

Plot expected number of events

opcharStopPlot()

Plot cumulative stopping probability by hypothesis

plot(<harmbound>)

Plot method for harmbound objects produced by getHarmBound

simSafetyStop()

Simulate safety stopping values. The effect can be given as proportion of events in the experimental group (pH1), the risk difference (rdH1), risk ratio (rrH1) or odds ratio (orH1).
