nodeId methods
These functions gives the node (nodeId) or edge
(edgeId) identity.
nodeId(x, type = c("all", "tip", "internal", "root"))
## S4 method for signature 'phylo4'
nodeId(x, type = c("all", "tip", "internal", "root"))
edgeId(x, type = c("all", "tip", "internal", "root"))
## S4 method for signature 'phylo4'

a character vector indicating which subset of the nodes or edges you are interested in. |
nodeId returns the node in ascending order, and
edgeId in the same order as the edges are stored in the
edge matrix.
an integer vector indicating node numbers
a character vector indicating the edge identity
