Data and R-Code from: How to account for behavioral states in step-selection analysis: a model comparison

This repository provides the R-code and data used for the simulation and case study of the research paper: "How to account for behavioral states in step-selection analysis: a model comparison".
The folder "Pohle_et_al_2023_BehavioralStates_iSSA_Data" contains the landscape rasters used for data generation in the simulation study, and the bank vole (Myodes glareolus) movement data used in the case study on bank vole interactions:

landscape10.RData and landscape50.RData: Landscape rasters for the simulation study.
Vole_case_control.rds: Case-control bank vole data for the case study.
Info_replicates.rds: Information about bank vole indiviuals and corresponding replicates for the case study.
Codebook_case_study.xlsx: Codebook for the case study data sets.

The folder "Pohle_et_al_2023_BehavioralStates_iSSA_RCode" contains the R-scripts for the simulation and case study:

Functions.R: Functions to apply HMMs, TS-iSSAs, and HMM-iSSAs to movement data; used for the simulation and case study.
Simulation_study.R: R-Code to run the simulation study. Parallel computation is used.
Results_simulation_study.R: R-Code to create the result figures and tables for the simulation study.
Case_study.R: R-Code to run the bank vole interaction case study. Parallel computation is used.
Results_case_study.R: R-Code to create the result figures and tables for the case study.

Besides the simulation and case study from the paper, the included functions (Functions.R) can generally be used to perform an HMM-iSSA analysis.
