Description

"simulation.R" : This file contains R codes to perform the following:

• Set up and perform simulations as described in the Appendix.

"figures.R" : This file contains R codes to perform the following:

• Produce figures presented in the paper based on the models fitted using "modelfit_monotonic.R".

"modelfit_monotonic.R" : This file contains R codes to perform the following:

• Model fitting for Red Kite breeding data, once with monotonic constraint and once unconstrained.

"plot_fun.R" : This file contains R codes to perform the following:

• Plotting functions to be used in "figures.R".

"bva.Rda", "variables.csv" : These files are R and csv data files:

• Red Kite breeding data for Bavaria and the variable description.

"redkite/XY.Rda" : This file is an R data file:

• Data required for plotting purposes only.

Rda files can be loaded into R as in R> load("bva.Rda")
