Hi, I am working with a phylog tree and I would like to extract a subset of the tree based on the species names (conserving the evolutionary distance and relationships between the pairs of species I am interested in). I see there is an option to select a subset of the tree using node names (phylog.extract), but this is not what I need since one node could take me to several species, some of which I am not interested in. This happens, for example, when I have a phylogenetic tree for, say, all bird species of North America, but I am only interested on those 20 that occur in my community, and I would like to extract the phylog tree for these species. Would anyone have any advice on how to proceed? Thanks a lot, Christine [[alternative HTML version deleted]]
