Find the grove for a group of chronograms and build a matrix.

This function implements theorem 1.1 of Ané et al. (2009) doi:10.1007/s00026-009-0017-x to find a grove for a given group of chronograms.

Usage

build_grove_matrix(datelife_result, n = 2)

Arguments

datelife_result

A datelifeResult object.

n

The degree of taxon name overlap among input chronograms. Defaults to n = 2, i.e., at least two overlapping taxon names.

Value

A matrix. Each cell shows whether n-overlap exists between a pair of inputs.
