Occurrence data for four species, and predictor variables called ModleR comes with example data, a list called example_occs with Twice in different output folders, for example). This partial flexibility allows for experimenting withįinal model and ensemble construction (by runnning final or ensemble ( final_dir = ""), to indicate the function where to lookįor models. To include the new value when calling ensemble_model() If youĬhange final_models default value ( "final_model") you will need The names of the final and ensemble folders can be modified,īut the nested subfolder structure will remain the same. The working directory (its default value is. You do not modify the default value, it will create the output under You can set models_dir wherever you want in the hard disk, but if When projecting models into the present, the projection folder isĬalled present, other projections will be named after their Obtaining one model per species per algorithmĮnsemble models join together the results obtained by different We define the final models as joining together the partitions and Training and test data set and one algorithm) We define a partition as the individual modeling round (one ModleR writes the outputs in the hard disk, according to the Ensemble: ensemble_model() joins the different models perĪlgorithm into an ensemble model (algorithmic consensus) using.Partition joining: final_model() joins the partition models into a.Model fitting and projecting: do_any() makes the ENM for oneĪlgorithm and partition optionally, do_many() calls do_any() to.It creates a metadataįile with details for the current round and a sdmdata file with the Pseudoabsences, and organizes the experimental design (bootstrap,Ĭrossvalidation or repeated crossvalidation).
