ANOVA-likestatisticaltestsfordifferencesamonggroupsareavailableforalmostahundredyears. But for large number of groups the results from commonly used post-hoc tests are often hard to in- terpret. To deal with this problem, the factorMerger package constructs and plots the hierarchical relation among compared groups. Such hierarchical structure is derived based on the Likelihood Ratio Test and is presented with the Merging Paths Plots created with the ggplot2 package. The cur- rent implementation handles one-dimensional and multi-dimensional Gaussian models as well as binomial and survival models. This article presents the theory and examples for a single-factor use cases.
