model_args function

Retrieve the arguments that a model-fitting function used

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

Returns

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.

Examples

# Segment a time series using Coen's algorithm
x <- segment(CET, method = "ga-coen", maxiter = 3)

# Recover the arguments passed to the model-fitting function
x |>
  as.segmenter() |>
  model_args()
