In the phyloseq package we provide optionally-parallelized methods for calculating both UniFrac and weighted-UniFrac, as well a few key UniFrac variants, all of which return a sample-wise distance matrix from any phyloseq object that contains both a phylogenetic tree and an otuTable (otuTree and its subclasses). In particular, more flexible models such as GAMLSS (Rigby and Stasinopoulos 2005) should be fitted in the nodes of a tree in order to capture location, scale, shape as well as censoring, tail behavior etc. Comparison with other R packages and a full list of unique features of ggtree can be found in Supplementary Material online.
