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