Calculate Variable Importance — calculate_sdm_variable

Calculate variable importance for one of the component models

Usage

calculate_sdm_variable_importance(
  mod,
  se,
  pa_col,
  xy_col,
  month_col,
  year_col,
  model
)

Arguments

mod: the output from make_sdm - only used for ensemble
se: data frame containing species presence/absence data and desired environmental covariate data.
pa_col: column name for presence/absence column
xy_col: a vector with a length of 2 indicating the longitude and latitude column names
month_col, year_col: column names for month and year columns respectively
model: one of the following indicating the desired model to calculate variable importance for: gam, maxent, brt, rf, or sdmtmb

Value

a vector of the variable importance for the given model. Each model calculates these differently, so the values should be normalized in order to compare across models.
