Format

A phylo object with 4 main parts

edge

The matrix edge contains the beginning and ending node number for all the nodes and tips in the tree. By convention, the tips of the tree are numbered 1 through n for n tips; and the nodes are numbered n + 1 through n + m for m nodes. m = n - 1 for a fully bifurcating tree. This is just to keep track of which nodes are internal and which are leaves.

tip.label

The vector tip.label contains the labels for all the tips in the tree. The order of tip.label is the order of the tips numbered 1 through n in edge.

edge.length

a vector of class "numeric" containing all the edge lengths of the tree in the same order as the rows in edge; and root.edge, a numeric value giving the length of the root edge, if one exists.

Nnode

The integer Nnode contains the number of internal nodes in the tree, including the root of the tree if the tree is rooted.
