Data for: Rapid evolution and cranial morphospace expansion during the terrestrial to marine transition in elapid snakes

<p dir="ltr">R script and data files to support the publication.</p><p dir="ltr">Analyses were completed in the R Statistical Environment, and the file "<b>Macroskull analyses.R</b>" can be used to recreate all analyses and figures in the publication.</p><p dir="ltr">The data files called by the script are as follows:</p><ol><li><b>Macroskull raw coords.tps</b> - 3D coordinate data for 63 landmarks placed on elapid skull models. There are 63 landmarks, but the script averages the position of two closely-positioned medially-paired landmarks to result in 62 landmarks for analysis</li><li><b>Macroskull classifier.csv</b> - metadata for 219 specimens from 91 species. Table gives <i>file_name</i>, the name of the skull model in the coordinate data file; <i>species, </i>the Latin binomial; <i>spec_number</i>, the museum identifier (see Supplementary materials Table S1 of publication for details); <i>species_abrev</i> and <i>species_abrev2</i>, codes for plotting species names; <i>Ecology</i> and <i>Ecology2</i>, codes for habitat classification, detailed in publication.</li><li><b>Elapid_tree_Lee2016.nex</b> - phylogenetic tree in nexus format from <a href="https://doi.org/10.1098/rsos.150277" target="_blank">https://doi.org/10.1098/rsos.150277</a></li><li><b>Elapid skull land pairs 62.csv</b> - medially-paired landmarks identified for generalised Procrustes superimposition taking into account left-right asymmetry.</li><li><b>Elapid skull links 62.csv</b> - landmark pairs for plotting landmark configuration with a wireframe.</li><li><b>Sidlauskas 2008 scripts</b> - folder of .R scripts from Brian Sidlauskas to perform mode analyses, which accompanied <a href="https://doi.org/10.1111/j.1558-5646.2008.00519.x" target="_blank">https://doi.org/10.1111/j.1558-5646.2008.00519.x</a></li></ol><p></p>
