Retrieve Covariates from a GHRmodels Object as a List of Character Vectors

Description

Extracts covariates from a GHRmodels object and returns them as a list of character vectors. If unique = TRUE, the output contains unique covariates across models. If unique = FALSE, the output preserves the original combinations of covariates as specified in the GHRmodels object.

get_covariates(model, unique = TRUE)

Arguments

  • model: A GHRmodels object containing fitted models.
  • unique: Logical; if TRUE, returns unique covariates across models. If FALSE, returns vectors of covariate combinations as declared in the GHRmodels object.

Returns

A list of character vectors.

Examples

## Not run:

# Load example dataset
data(dengueMS)

# Declare formulas
formulas <- c(
  "dengue_cases ~ tmin +  f(year, model='rw1')",
  "dengue_cases ~ pdsi +  f(year, model='rw1')"
)

# Tranform formulas into a 'GHRformulas' object
ghr_formulas <- as_GHRformulas(formulas)

# Fit multiple models 
results <- fit_models(
  formulas = ghr_formulas,
  data     = dengue_MS,
  family   = "nbinomial",
  name     = "TestModel",
  offset   = "population",
nthreads = 2,
control_compute = list(config = FALSE),
pb       = TRUE
)

# Extract the list of covariates from the models 
get_covariates(results)
