In this example, we will calculate the ensemble consistency index (CI) and ensemble retention index (RI). The CI and RI both measure the degree of "tree-likeness" in data under a parsimony model for character change. We will use the free programs Mesquite (Maddison and Maddison 2006) and R (R Core Development Team 2010) to calculate CI and RI. If you did not yet install Mesquite, you can go here for download and installation instructions. You can download R from here.
