findSibling {TreeSummarizedExperiment} | R Documentation |
findSibling
is to find the sibling node of an node
node.
findSibling(tree, node, use.alias = FALSE)
tree |
A phylo object. |
node |
A numeric or character vector. Node labels or node numbers. |
use.alias |
A logical value, TRUE or FALSE. The default is FALSE, and
the original 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
.
