Welcome

Developed for practical use: below you find a collection of practical examples and use-cases, the so-called rpact vignettes.

In addition to these public open access vignettes, our RPACT SLA customers have access to exclusive vignettes on special topics such as the analysis of multi-stage data with covariates from raw data.

#	Title Sort ascending	Category	Endpoint	Summary
11	Comparing Sample Size and Power Calculation Results for a Group Sequential Trial with a Survival Endpoint: rpact vs. gsDesign	Planning	Survival	This R Markdown document provides an example that illustrates how to compare sample size and power calculation results of the two different R packages rpact and gsDesign.
21	Analysis of a Multi-Arm Design with a Binary Endpoint using rpact	Analysis	Categorical	This R Markdown document shows how to analyse and interpret multi-arm designs for testing proportions with rpact. Multi-arm
7	Analysis of a Group Sequential Trial with a Survival Endpoint using rpact	Analysis	Survival	This R Markdown document provides examples how to analyse a survival trial and provide inference throughout and at the end of the trial with rpact.
6	An Example to Illustrate Boundary Re-Calculations during the Trial with rpact	Planning	Survival	This R Markdown document provides an example for updating the group sequential boundaries when using an alpha-spending function approach based on observed information rates in rpact. Since version 3.1 of rpact, an additional option in the `getAnalysisResults()` function provides an easy way to perform an analysis with critical values that are calculated subsequently during the stages of the trial.
