- The depth of a node is computed as the number of tips which are its
- descendants. The value of 1 is given to the tips.
+ \code{node.depth} computes the depth of a node as the number of tips
+ which are its descendants. The value of 1 is given to the tips.
+
+ \code{node.depth.edgelength} does the same but using branch lengths.
+
+ \code{node.height} computes the heights of nodes and tips as plotted
+ by a phylogram.
+
+ \code{node.height.clado} does the same but for a cladogram.
