scripts

• help_functions.R: helper functions
• master.R: master script running all subscripts in /R
• plot_functions.R: helper functions for plotting
• plots.R: script to produce plots for manuscript, also running supplement.Rmd

• /R: scripts used to check and prepare data before modelling and modelling process (sourced by master.R)
  • mergeCali.R: merges position estimates with GPS fixes and station cover
  • Model_PE.R: modelling process (m1, m2, m3.1, m3.2, m3.3 and predictive performance tests)
