Description

This functions sums all species records into one. Should be used before the data cleaning routine.

Usage

use_mem(x, add = TRUE, name = "MEM")

Arguments

`x`	A `occurrences` or `input_sdm` object containing occurrences.
`add`	Logical. Should the new MEM records be added to the pool (`TRUE`) of species or the output should have only the summed records (`FALSE`)? Standard is `TRUE`.

Examples

# Create sdm_area object:
sa <- sdm_area(parana, cell_size = 25000, crs = 6933)

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

# Include scenarios:
sa <- add_scenarios(sa)

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

# Create input_sdm:
i <- input_sdm(oc, sa)

# Use MEM:
i <- use_mem(i)
