Simplified phylogenetic tree
WebbHere is a familiar example that everyone will know about – a family tree (Figure 4). You will probably already know how to interpret patterns of relatedness on a family tree, and it turns out that the same principles apply to phylogenetic trees more generally. Figure 4 A simple family tree. In Figure 4 we can see that you are more closely ... WebbThis is simply a means to generate a random tree. With the n = 4 argument, we are simply stating our tree will have four taxa and we are already specifying what they should be called with the tip.label argument. Let’s take a closer look at our tree object. It is a phylo object - you can demonstrate this to yourself with class (tree).
