Plots an ellipse
Extracts a vector of ancestors for a given taxon. Code written by Jonathan S. Mitchell for
Zelditch et al. (2017)
Quantify convergence by the number of convergent events
Reconstructs ancestral states for multiple characters
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)
Computes Ct values for a pair of tips. Internal, called in calcConv.
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.
Plots calcConv or convSig output.
Assess the significance of convergent evolution using simulations and the convnum metric
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.

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.
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).
