Analyses of Phylogenetics and Evolution

ape provides functions for reading, writing, plotting, and manipulating phylogenetic trees, analyses of comparative data in a phylogenetic framework, analyses of diversification and macroevolution, computing distances from allelic and nucleotide data, reading nucleotide sequences, and several tools such as Mantel's test, computation of minimum spanning tree, the population parameter theta based on various approaches, nucleotide diversity, generalized skyline plots, estimation of absolute evolutionary rates and clock-like trees using mean path lengths, non-parametric rate smoothing and penalized likelihood, classifying genes in trees using the Klastorin-Misawa-Tajima approach. Phylogeny estimation can be done with the NJ, BIONJ, and ME methods.
