A rooted phylogenetic tree (see two graphics at top) is a directed tree with a unique node — the root — corresponding to the (usually imputed) most recent common ancestor of all the entities at the leaves of the tree. The root node does not have a parent node, but serves as the parent of all other nodes in the tree. The root is therefore a node of degree 2, while other internal nodes have a mini… WebJul 24, 2024 · I need to root the tree so I tried this: rooted_tree = root (computed_brlen_tree, outgroup = "Russula_foetens", resolve.root = TRUE) it changes how the tree looks, and I …
