Lightweight Graph Based Multiple Comparison Procedures

A lightweight fork of 'gMCP' with functions for graphical described multiple test procedures introduced in Bretz et al. (2009) and Bretz et al. (2011) . Implements a flexible function using 'ggplot2' to create multiplicity graph visualizations. Contains instructions of multiplicity graph and graphical testing for group sequential design, described in Maurer and Bretz (2013) , with necessary unit testing using 'testthat'.

gMCPLite

gMCPLite is a fork of gMCP for graph-based multiple comparison procedures, with the following features:

• Kept a selected subset of the original functions.
• Removed the rJava dependency and the Java-based graphical interface.
• Added an hGraph() function for ggplot2 visualizations. It bridges gMCP result objects and gsDesign to produce multiple comparison graphs and sequential graph updates.

A Shiny app is also available to generate graphs of multiple comparisons and update graphs based on graphical approach.

Installation

# The easiest way to get gMCPLite is to install:
install.packages("gMCPLite")

# Alternatively, install development version from GitHub:
# install.packages("remotes")
