How to create one- and multi-arm simulation result plots with rpact

Summary

This R Markdown document provides many different examples for creating one- and multi-arm simulation result plots with rpact and ggplot2.

1 Preparation

First, load the rpact package

library(rpact)
packageVersion("rpact") 

## [1] '3.2.1'

2 Simulation results base

2.1 Simulation results base - means

maxNumberOfSubjects <- 90
informationRates <- c(0.2, 0.5, 1)
plannedSubjects <- round(informationRates * maxNumberOfSubjects)
design <- getDesignInverseNormal(futilityBounds = c(-0.5, 0.5), informationRates = informationRates)
x <- getSimulationMeans(design = design, groups = 2, meanRatio = TRUE, thetaH0 = 0.4, 
    plannedSubjects = plannedSubjects, maxNumberOfIterations = 500, 
    allocationRatioPlanned = 3, stDev = 1.5, seed = 1234567890)
plot(x, type = "all", grid = 0)
