shareNode {TreeSummarizedExperiment} | R Documentation |
shareNode
is to find the node where the specified nodes first meet.
shareNode(tree, node, use.alias = FALSE)
tree |
A phylo object. |
node |
A vector of node numbers or node labels. |
use.alias |
A logical value, TRUE or FALSE. The default is FALSE, and
the node label would be used to name the output; otherwise, the alias of
node label would be used to name the output. The alias of node label is
created by adding a prefix |
A vector of nodes. The numeric value is the node number, and the
vector name is the corresponding node label. If a node has no label, it
would have NA as name when use.alias = FALSE
, and have the alias of
node label as name when use.alias = TRUE
.
