In treestats: Phylogenetic Tree Statistics
four_prong R Documentation
Four prong index
Description
Calculate the number of 4-tip caterpillars. The function does
accept non-binary trees, but four-prongs are only calculated on
non-polytomous sub-trees with 4 tips, e.g. the 4-tip part has to be a
caterpillar.
Usage
four_prong(input_obj)
Arguments
input_obj
phylo object or ltable
Value
number of 4-tip caterpillars
