Biomass equations for Spanish softwood species

eq_biomass_ruiz_peinado_2011.Rd

Allometric equations adjusted for Spanish softwood species

Usage

eq_biomass_ruiz_peinado_2011(species, component = "stem", return_rmse = FALSE)

Arguments

species

A character string specifying the scientific name of the tree species. It can be a column name if all the species are included in this model. See Details for available species.

component

A character string specifying the tree component for biomass calculation (e.g., "tree", "stem", "branches"). See Details.

return_rmse

A logical value. If TRUE, the function returns the root mean squared error (RMSE) of the selected model instead of the biomass value.

Value

A S7 list of parameters

Details

Users can check the list of supported species and their corresponding components in biomass_models.
