When a queried species is absent from the mega-tree, it is grafted onto the tree using one of two placement strategies: attachment at the basal node of the most closely related genus or family (''at_basal_node''), or random attachment below that basal node with probability proportional to branch length (''random_below_basal''). See Li (2023) for details. Multiple species from a genus not represented in the mega-tree are placed as a polytomy to preserve clade coherence. The package interfaces with the ''megatrees'' data package, which bundles or downloads on demand curated mega-trees. Users can also provide their own mega-trees.' authors: - family-names: Li given-names: Daijiang email: daijianglee@gmail.com orcid: https://orcid.org/0000-0002-0925-3421 preferred-citation: type: article title: 'rtrees: an R package to assemble phylogenetic trees from megatrees' authors: - family-names: Li given-names: Daijiang email: daijianglee@gmail.com orcid: https://orcid.org/0000-0002-0925-3421 journal: Ecography year: '2023' volume: '2023' issue: '7' url: https://github.com/daijiang/rtrees start: e06643 repository: https://cran.r-universe.dev commit: bcb28364b7380417caf6be7f3e62fbc6bda0d031 url: https://daijiang.github.io/rtrees/ date-released: '2026-06-11' contact: - family-names: Li given-names: Daijiang email: daijianglee@gmail.com orcid: https://orcid.org/0000-0002-0925-3421
