basicPlot {bpp}

R Documentation

Basic plot functions to illustrate prior and posterior densities when considering a time-to-event endpoint

Description

Basic plot function, labels are specific to the hazard ratio, i.e. when looking at a time-to-event endpoint.

Usage

basicPlot(leg = TRUE, IntEffBoundary = NA, IntFutBoundary = NA, successmean = NA, 
       priormean = NA)

Arguments

leg	logical, display legend?
IntEffBoundary	Interim efficacy boundary.
IntFutBoundary	Interim futility boundary.
successmean	The mean that defines success at the final analysis. Typically chosen to be the minimal detectable difference, i.e. the critical on the scale of the effect size of interest corresponding to the significance level at the final analysis.
priormean	Mean of the prior.

Value

Empty generic plot.
