findDescendant
finds descendants of a node.
findOS(tree, node, only.leaf = TRUE, self.include = FALSE, use.alias = FALSE) findDescendant( tree, node, only.leaf = TRUE, self.include = FALSE, use.alias = FALSE )
tree |
A phylo object. |
node |
An internal node. It could be the node number or the node label. |
only.leaf |
A logical value, TRUE or FALSE. The default is TRUE. If default, only the leaf nodes in the descendant nodes would be returned. |
self.include |
A logical value, TRUE or FALSE. The default is FALSE. If TRUE, the node specified in node is included and the leaf node itself is returned as its descendant. |
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
.
