Details

This function is key in this SDM workflow. It attaches cell_id values to occ, deletes records outside pred and allows the use of pseudoabsences. This function also tests if CRS from both occ and pred are equal, otherwise the CRS of pred is used to convert occ.

Examples

# Create sdm_area object:
sa <- sdm_area(parana, cell_size = 50000, crs = 6933)

# Include predictors:
sa <- add_predictors(sa, bioc) |> select_predictors(c("bio1", "bio4", "bio12"))

# Include scenarios:
sa <- add_scenarios(sa, scen)

# Create occurrences:
oc <- occurrences_sdm(occ, crs = 6933) |> join_area(sa)
