Arguments

`sp`	A `vector`, a `SpatVector` without associated data (if presence-only), or a `SpatVector` object containing binary data (`0` : absence, `1` : presence, `NA` : indeterminate) for a single species that will be used to build the species distribution model(s) Note that old format from sp are still supported such as `SpatialPoints` (if presence-only) or `SpatialPointsDataFrame` object containing binary data.
`env`	a `matrix`, `data.frame`, `SpatVector` or `SpatRaster` object containing the explanatory variables (in columns or layers) that will be used to build the species distribution model(s). Note that old format from raster and sp are still supported such as `RasterStack` and `SpatialPointsDataFrame` objects.
`xy`	(optional, default `NULL`) If `resp.var` is a `vector`, a 2-columns `matrix` or `data.frame` containing the corresponding `X` and `Y` coordinates that will be used to build the species distribution model(s)
`dir.name`	a `character` corresponding to the modeling folder
`sp.name`	a `character` corresponding to the species name
`eval.sp`	(optional, default `NULL`) A `vector`, a `SpatVector` without associated data (if presence-only), or a `SpatVector` object containing binary data (`0` : absence, `1` : presence, `NA` : indeterminate) for a single species that will be used to evaluate the species distribution model(s) with independent data Note that old format from sp are still supported such as `SpatialPoints` (if presence-only) or `SpatialPointsDataFrame` object containing binary data.
`eval.env`	(optional, default `NULL`) A `matrix`, `data.frame`, `SpatVector` or `SpatRaster` object containing the explanatory variables (in columns or layers) that will be used to evaluate the species distribution model(s) with independent data Note that old format from raster and sp are still supported such as `RasterStack` and `SpatialPointsDataFrame` objects.
`eval.xy`	(optional, default `NULL`) If `resp.var` is a `vector`, a 2-columns `matrix` or `data.frame` containing the corresponding `X` and `Y` coordinates that will be used to evaluate the species distribution model(s) with independent data
`na.rm`	(optional, default `TRUE`) A `logical` value defining whether points having one or several missing values for explanatory variables should be removed from the analysis or not
`data.mask`	(optional, default `NULL`) A `SpatRaster` object containing the mask of the studied area
`shared.eval.env`	(optional, default `FALSE`) A `logical` value defining whether the explanatory variables used for the evaluation dataset are the same than the ones for calibration (if `eval.env` not provided for example) or not
`filter.raster`	(optional, default `FALSE`) If `env` is of raster type, a `logical` value defining whether `sp` is to be filtered when several points occur in the same raster cell
`object`	a `BIOMOD.formated.data` object

data.env.var: a data.frame containing explanatory variables
data.mask: a SpatRaster object containing the mask of the studied area
