findChild finds children of an internal node.
A phylo object.
An internal node. It could be the node number or the node label.
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.
