WebImplements random spatial thinning algorithm Description. thin.algorithm implements a randomization approach to spatially thinning species occurence data. This function is the algorithm underlying the thin function.. Usage thin.algorithm(rec.df.orig, thin.par, reps) WebFor temporal thinning, the function first splits occurrence records into grid cells of given size in degrees (set by spatial.split.degrees ). This is to prevent spatially distant but temporally close records from being excluded. For each grid cell, all records within the cell are temporally thinned. This process works by removing records that ...

WebFor this reason, we selected SOR using the procedure of ran- dom filtration of subsamples using the spThin package (Aiello-Lammens et al. 2015). This procedure is designed to (1) decrease the spatial bias of SOR located in different parts of the species range and (2) reduce the SAC of residuals of the model using ap- proaches described by Dormann et al. … Web15 Mar 2024 · My idea is that since SpThin is made with the idea that you will get the most presences this is not needed for species where you have a ton of presences.
