Phylogenetic Ridge Regression Methods for Comparative Studies R package RRphylo version 3.0.2 CRAN Task View: Paleontology (https://CRAN.R-project.org/view=Paleontology) Functions for phylogenetic analysis (Castiglione et al., 2018 <doi:10.1111/2041-210X.12954>). The functions perform the estimation of phenotypic evolutionary rates, identification of phenotypic evolutionary rate shifts, quantification of direction and size of evolutionary change in multivariate traits, the computation of ontogenetic shape vectors and test for morphological convergence.
