Retrieve the arguments that a model-fitting function used

Usage

model_args(object, ...)

# Default S3 method
model_args(object, ...)

# S3 method for class 'seg_cpt'
model_args(object, ...)

# S3 method for class 'ga'
model_args(object, ...)

# S3 method for class 'cpt'
model_args(object, ...)

# S3 method for class 'wbs'
model_args(object, ...)

Arguments

object

A segmenter object.

...

currently ignored

Value

A named list of arguments, or NULL

Details

Every model is fit by a model-fitting function, and these functions sometimes take arguments. model_args() recovers the arguments that were passed to the model fitting function when it was called. These are especially important when using a genetic algorithm.
