Data and scripts underlying the publication: Unveiling the roles of temporal periodicity, the spatial environment and behavioural modes in terrestrial animal movement. The RData file Linssen_2024_JMovEcol_data contains everything needed to be able to run the code for the analysis:- Data tables with location data (timestamp, x, y...), one for each species. These data have been pre-processed, cleaned and annotated with environmental covariates as described in the manuscript.- A custom function collectmuHMMoutput(), which is used to collect all the relevant components of a HMM fit (the model itself, starting parameters, Viterbi decoding et cetera) into one list object.- A custom function mutatePar0(), which takes starting parameters for a model and creates four sets of perturbations of those starting values (as described in the manuscript under Model fitting). The R file Linssen_2024_JMovEcol_script contains the code needed to run the analysis. The code can be ran from top to bottom to run the analysis for eland; for wildebeest and zebra the "species" parameter in line 13 should be set to either of these.
