要旨:
Classifications of languages into language families, such as provided by Ethnologue, Glottolog, WALS and AUTOTYP, usually come in non-standard formats and do not provide branch lengths, making them very hard to use by various software tools such as phylogenetic programs.
This resource introduces a flexible method (written in R) for (a) converting these representations into the standard Newick format and (b) for adding branch length information from a variety of sources.
More information can be found in the README.md file and in the paper/family-trees-with-brlength.pdf files in the GitHub repository.
