nodeId: nodeId methods

Description

These functions gives the node (nodeId) or edge (edgeId) identity.

Usage

nodeId(x, type = c("all", "tip", "internal", "root"))
# S4 method for phylo4
nodeId(x, type = c("all", "tip", "internal", "root"))
edgeId(x, type = c("all", "tip", "internal", "root"))
# S4 method for phylo4
edgeId(x, type = c("all", "tip", "internal", "root"))

Arguments

x

a phylo4 or phylo4d object.

type

a character vector indicating which subset of the nodes or edges you are interested in.

Value

nodeId

an integer vector indicating node numbers

edgeId

a character vector indicating the edge identity

Details

nodeId returns the node in ascending order, and edgeId in the same order as the edges are stored in the edge matrix.

Examples

# NOT RUN {
  data(geospiza)
  identical(nodeId(geospiza, "tip"), 1:nTips(geospiza))
  nodeId(geospiza, "internal")
  edgeId(geospiza, "internal")
  nodeId(geospiza, "root")
# }
