Covariate used is elevation, from the Piceance Basin NW Colorado. Northrup_et_al_sim2.R: Simulation of use-availability data as a point process at 3rd/4th order scale and fitting of resource selection functions with varying availability samples that are matched or mismatched to the used sample. Covariates simulated as Gaussian random field. Northrup_et_al_sim3.R: Simulation of use-availability data as a point process at 3rd order scale and fitting of resource selection functions with varying availability samples that are matched or mismatched to the used sample. Covariates simulated as Gaussian random field. Northrup_et_al_deer.R: Code for testing convergence of resource selection function coefficients as a function of availability sample size for one mule deer and 3 covariates, elevation, distance to roads, and slope. avail.file.R: Environmental covariates at available locations used in "Northrup_et_al_deer.R" code. used.file.R: Environmental covariates at used locations used in "Northrup_et_al_deer.R" code. elev_simple.asc: ASCII file of elevation in the Piceance Basin, for use in "Northrup_et_al_sim1.R."
