For a given clustering, walks the walktrap result tree to find a subtree with max(min(sens,spec)) for each cluster, where sens is sensitivity, spec is specificity
bestClusterThresholds(res, clusters, clmerges = NULL)
a list of $thresholds - per cluster optimal detectability values, and $node - internal node id (merge row) where the optimum was found
walktrap result object (igraph)
cluster factor
integer matrix of cluster merges (default=NULL). If NULL, the function treeJaccard() performs calculation without it.
