Functions support trait data\nintegration, taxon-specific trait extraction, coverage\nassessment, optional principal component analysis, and\nestimation of phylogenetic signal using Pagel's lambda or\nBlomberg's K. Curated quantitative trait datasets are included\nfor plants, birds, mammals, reptiles, amphibians, and fishes.\nPaired simulations assess how observed patterns of missing\ntrait data affect Pagel's lambda estimates and significance\nclassifications for individual traits. Methods for quantifying\nphylogenetic signal are based on Pagel (1999)\n, Blomberg et al. (2003)\n, and Münkemüller et\nal.
