DDRTree\nshows superiority to alternatives (Wishbone, DPT) for inferring\nthe ordering as well as the intrinsic structure of the single\ncell genomics data. In general, it could be used to reconstruct\nthe temporal progression as well as bifurcation structure of\nany datatype.", "License": "Artistic License 2.0", "RoxygenNote": "6.0.1",
