02_sister_pairs.zip

This file contains data and R code for the sister pairs analyses. There are 2 files. 'raw_data_sister_pairs.csv' is a comma separated values file that contains all of the branch length and life history data we used in the sister pairs analyses. There is one row per sister pair in the analysis, which has data on: the two families in the sister pair, the proportion of genera we had height data for in each family, the number of species in each family, the average height of each family (log transformed value in mm), nuclear branch length for each family (in units of substitutions/site), chloroplast dN branch length for each family (also in substitutions/site), chloroplast dS branch length for each family (also in substitutions/site), Latitude for each family (in distance from the equator), UV for each family (measured as in Davies et al 2004), and Temperature for each family (in Kelvins). 'sister_pairs_analyses.r' contains all R code used for the sister pairs analyses. To use it, you will need to download R (it's free), install the relevant packages (at the top of the .r file), and then change the line at the top which starts 'setwd' to point to the folder on your computer that contains the raw_data_sister_pairs.csv file. As you go through the R code, it will print out all of the results in the paper that used sister pairs analyses.
