maxent_plot_variable_importance(
  contributions_df,
  perm_imp_df,
  species,
  output_dir
)

Arguments

contributions_df

A data.frame with columns name and contribution (from maxent_percent_contribution).

perm_imp_df

A data.frame with columns name and permutation_importance (from maxent_permutation_importance).

species

Character: species name (used in the filename).

output_dir

Character: directory under which a plots/ sub-directory will be created.

Value

Invisibly returns the path to the PNG file.

Examples

if (FALSE) { # \dontrun{
maxent_plot_variable_importance(contrib, perm_imp,
  species = "Sp1", output_dir = tempdir())
} # }
