Get 50 randomly selected mega-trees of 31516 Fish from The Fish Tree of Life

Description

This tree was generated by Rabosky et al. (2018). It has 31516 tips, with species missing sequence data added using birth-death models. The authors suggest not using these trees for trait evolution analyses. Because of the large file size (~23 MB), this dataset is not bundled with the package and is downloaded and cached locally on first use.

Usage

get_tree_fish_32k_n50(force = FALSE)

Arguments

force

Logical. Re-download even if a local cache exists. Default FALSE.

Value

A multiPhylo object. Each phylogeny also has a data frame genus_family_root with root node information for every unique genus and family, usable for inserting new tips onto the phylogeny.
