Package: surface Type: Package Title: Fitting Hansen Models to Investigate Convergent Evolution Version: 0.6 Date: 2024-08-19 Authors@R: person(given = "Travis", family = "Ingram", role = c("aut", "cre"), email = "travis.ingram@otago.ac.nz") Depends: R (>= 2.6), ape, ouch, MASS, geiger Suggests: igraph Imports: methods, phytools Description: This data-driven phylogenetic comparative method fits stabilizing selection models to continuous trait data, building on the 'ouch' methodology of Butler and King (2004) . The main functions fit a series of Hansen models using stepwise AIC, then identify cases of convergent evolution where multiple lineages have shifted to the same adaptive peak.
