Get the terms of a model

Source: R/model_get_terms.R
model_get_terms.Rd

Return the result of stats::terms() applied to the model or NULL if it is not possible to get terms from model.

Usage

model_get_terms(model)

# Default S3 method
model_get_terms(model)

# S3 method for class 'brmsfit'
model_get_terms(model)

# S3 method for class 'glmmTMB'
model_get_terms(model)

# S3 method for class 'model_fit'
model_get_terms(model)

# S3 method for class 'betareg'
model_get_terms(model)

# S3 method for class 'betareg'
model_get_terms(model)

Arguments

model

(a model object, e.g. glm)
A model object.

Details

For models fitted with glmmTMB::glmmTMB(), it will return a terms object taking into account all components ("cond" and "zi"). For a more restricted terms object, please refer to glmmTMB::terms.glmmTMB().
