RERconverge: an R package for associating evolutionary rates with convergent traits.

ABSTRACT

MOTIVATION When different lineages of organisms independently adapt to similar environments, selection often acts repeatedly upon the same genes, leading to signatures of convergent evolutionary rate shifts at these genes. With the increasing availability of genome sequences for organisms displaying a variety of convergent traits, the ability to identify genes with such convergent rate signatures would enable new insights into the molecular basis of these traits. RESULTS: Here we present the R package RERconverge, which tests for association between relative evolutionary rates of genes and the evolution of traits across a phylogeny. RERconverge can perform associations with binary and continuous traits, and it contains tools for visualization and enrichment analyses of association results. AVAILABILITY AND IMPLEMENTATION RERconverge source code, documentation and a detailed usage walk-through are freely available at https//github.com/nclark-lab/RERconverge. Datasets for mammals, Drosophila and yeast are available at https//bit.ly/2J2QBnj. SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online.
