The package uses a parametric spike-and-slab Bayesian model to downweight the effect of noise variables and to quantify the importance of each variable in agglomerative clustering. We take advantage of the existence of closed-form marginal distributions to estimate the model hyper-parameters using empirical Bayes, thereby yielding a fully automatic method. We discuss computational problems arising in implementation of the procedure and illustrate the usefulness of the package through examples.agglomerative clusteringBayesian clusteringBayesian variable selectiondendrogramhierarchical clusteringRspike-and-slab modelGeometric RepresentationMicroarray ExperimentsExpression DataMixture ModelRegressiontext::journal::journal article::research article
