Update a lcModel

Source: R/model.R

Fit a new model with modified arguments from the current model.

# S3 method for class 'lcModel'
update(object, ...)

Arguments

object

The lcModel object.

...

Arguments passed on to latrend

method

An lcMethod object specifying the longitudinal cluster method to apply, or the name (as character) of the lcMethod subclass to instantiate.

data

The data of the trajectories to which to estimate the method for. Any inputs supported by trajectories() can be used, including data.frame and matrix.

envir

The environment in which to evaluate the method arguments via compose(). If the data argument is of type call then this environment is also used to evaluate the data argument.

verbose

The level of verbosity. Either an object of class Verbose (see R.utils::Verbose for details), a logical indicating whether to show basic computation information, a numeric indicating the verbosity level (see Verbose), or one of c('info', 'fine', 'finest').

Value

The refitted lcModel object, of the same type as the object argument.

Examples

data(latrendData)
method <- lcMethodLMKM(Y ~ Time, id = "Id", time = "Time")
model2 <- latrend(method, latrendData, nClusters = 2)

# fit for a different number of clusters
model3 <- update(model2, nClusters = 3)
