Edges accessors
Access or modify information about the edges.

Optional arguments used by specific methods. (None used at present). |
drop.root |
logical (default FALSE), should the edge connecting the root be included in the edge matrix? |
edgesreturns the edge matrix that represent the ancestor-descendant relationships among the nodes of the tree.
edgeOrderreturns the order in which the edge matrix is in.
internalEdgesreturns a logical vector indicating
internal edges (edges that connect an internal node to
another). This vector is named with the edgeId
.
terminalEdgesreturns a logical vector indicating
terminal edges (edges that connect an internal node to a
tip). This vector is named with the edgeId
