The supplementary material here contains the necessary data and scripts to reproduce our analysis. It also contains additional data and analyses (SI1-5).
The file 'raw data.csv' contains the data used to calculate mean effect sizes. More information about its content can be found in the markdown file 'codebook.md'.
The main script to run our analysis is 'analysis.R'. It automatically executes the other R scripts that we provided here:
- 'calculate_smd.R' (function that uses equations found in our methods section to calculate standardized mean differences)
- 'phylogeny.R' (function that creates phylogeny trees)
- 'significance.R' (function that performs pairwise comparisons)
