Graphical approaches for multiple comparison procedures (MCPs) are a general framework to control the family-wise error rate strongly at a pre-specified significance level \(0<\alpha<1\). This approach includes many commonly used MCPs as special cases and is transparent in visualizing MCPs for better communications. graphicalMCP
is designed to design and analyze graphical MCPs in a flexible, informative and efficient way.

which removes the rJava dependency - gMCPLiteBuilt upon these packages, we hope to implement graphical MCPs in a more general framework, with fewer dependencies and simpler S3 classes, and without losing computational efficiency.
AcknowledgmentsAlong with the authors and contributors, thanks to the following people for their suggestions and inspirations on the package:
Frank Bretz, Willi Maurer, Ekkehard Glimm, Nan Chen, Jeremy Wildfire, Spencer Childress, Colleen McLaughlin, Matt Roumaya, Chelsea Dickens, Nan Xiao, Keaven Anderson, and Ron Yu
We owe a debt of gratitude to the authors of gMCP for their pioneering work, without which this package would not be nearly as extensive as it is.
