| sizedsubtree {RRphylo} | R Documentation |
Find a node subtending to a clade of desired size
Description
The function sizedsubtree scans a phylogentic tree to
randomly find nodes subtending to a subtree of desired minimum size, up to
one half of the tree size (number of tips).
Usage
sizedsubtree(tree,Size=NULL,time.limit=10)
Arguments
tree |
a phylogenetic tree. |
Size |
the desired size of the tree subtending to the extracted node. By default, the minimum tree size is set at one tenth of the tree size (i.e. number of tips). |
time.limit |
specifies a limit to the searching time, a warning message is thrown if the limit is reached. |
Details
The argument time.limit sets the searching time. The
algorithm stops if that limit is reached, avoiding recursive search when no
solution is in fact possible.
Value
A node subtending to a subtree of desired minimum size.
