calcConv                Quantifies convergent evolution by the ratio of
                        the current to maximum past phenotypic distance
                        between two or more lineages, as described in
                        Stayton (2015). Code written by Jonathan S.
                        Mitchell for Zelditch et al. (2017).
calcConvCt              Computes Ct-metric scores for putatively
                        convergent tips (or groups of tips) given a set
                        of user provided phenotypic characters and a
                        time calibrated phylogeny.
calcCs                  Calculates the C1-C4 measures of convergent
                        evolution between two lineages as described in
                        Stayton (2015). All measures quantify
                        convergence by the ratio of current to maximum
                        past phenotypic distance between lineages. Can
                        be used as-is but more often will be used
                        within the calcConv script. Code written by
                        Jonathan S. Mitchell for Zelditch et al. (2017)
calcCsCt                Computes Ct values for a pair of tips.
                        Internal, called in calcConv.
convSig                 Uses simulations to assess the significance of
                        C1-C4 measures of convergent evolution as
                        described in Stayton (2015). Code written by
                        Jonathan S.  Mitchell for Zelditch et al.
                        (2017)
convSigCt               Computes and conducts significance tests on
                        Ct-metric scores for putatively convergent tips
                        (or groups of tips) given a set of user
                        provided phenotypic characters and a time
                        calibrated phylogeny.
convnum                 Quantify convergence by the number of
                        convergent events
convnumsig              Assess the significance of convergent evolution
                        using simulations and the convnum metric
multianc                Reconstructs ancestral states for multiple
                        characters
plotCt                  Plots calcConv or convSig output.
plotellipse             Plots an ellipse
pullNodeSeq             Extracts a vector of ancestors for a given
                        taxon. Code written by Jonathan S. Mitchell for
                        Zelditch et al. (2017)
