The structure of the object returned by stats::model.frame()
could slightly differ for certain types of models.
model_get_model_frame()
will always return an object
with the same data structure or NULL
if it is not possible
to compute model frame from model
.
model_get_model_frame(model)
# S3 method for default
model_get_model_frame(model)
# S3 method for coxph
model_get_model_frame(model)
# S3 method for survreg
model_get_model_frame(model)
# S3 method for biglm
model_get_model_frame(model)
# S3 method for model_fit
model_get_model_frame(model)
# S3 method for fixest
model_get_model_frame(model)
a model object
