update.RdThe update function provides a unified interface for refreshing or modifying
existing analysis objects produced by the Qval package, including CDM,
validation, and sim.data classes. By passing additional arguments,
users can rerun fitting or simulation routines without reconstructing the entire object
from scratch.
update(x, ...)
# S3 method for class 'CDM'
update(x, ...)
# S3 method for class 'validation'
update(x, ...)
# S3 method for class 'sim.data'
update(x, ...)An object of class CDM, validation,
and sim.data.
Additional arguments specific to the method being updated:
For CDM: Y, Q, model, method,
mono.constraint, maxitr, verbose.
For validation: Y, Q, CDM.obj, par.method,
mono.constraint, model, method, search.method,
iter.level, maxitr, eps, alpha.level, criter,
verbose.
For sim.data: Q, N, IQ, model,
distribute, control, verbose.
An updated object of the same class as x, reflecting any changes
in the supplied parameters.
The update methods internally extract the original call arguments
from the input object, combine them with any new parameters provided in
..., and re-invoke the corresponding constructor (CDM,
validation, and sim.data). This approach ensures consistency
and preserves all untouched settings from the original object.
update(CDM): Update method for CDM objects
update(validation): Update method for validation objects
update(sim.data): Update method for sim.data objects
