Matrix representation parsimony (MRP) supertree es.Order of traits in brownie.lite() and evol.vcv().For fun: least squares phylogeny estimation.There are two main types of plums, European and Japanese, being marketed today. Today there are more than 200 cultivars being grown. Plums are native to China, America, and Europe. Now, say we want to keep the species t2, t4, t6, t8, and t10 in our pruned tree, we just put these tip names into a vector: Trina Roberts (now at NESCent) shared a trick to do this with me some time ago, and I thought I'd pass it along to the readers of this blog.įirst, let's start with a tree of 10 species: However, it is not immediately obvious how to prune the tree to include, rather than exclude, a specific list of tips. Using the function drop.tip() we can easily excise a single taxon or a list of taxa from our "phylo" tree object in R.
