Asynchrony of ageing among traits in a wild bird population

Data and code for analysis in manuscript titled "Asynchrony of ageing among traits in a wild bird population" Dataframes ending with"_28_5.csv" and "survival_model.csv" are used in scripts model1-13, of which the output is plotted using "new model outputs.R" Code for Figures 1 and 2 are in script "new model outputs.R" asymmetry bivar ver3.R runs the bivariate models used to estimate the degree of synchrony of ageing. scripts starting with "aic.." are used in the analysis for age by lifespan interaction
