coef.lcModel: Extract lcModel coefficients

In latrend: A Framework for Clustering Longitudinal Data

Extract lcModel coefficients

Description

Extract the coefficients of the lcModel object, if defined. The returned set of coefficients depends on the underlying type of lcModel. The default implementation checks for the existence of a coef() function for the internal model as defined in the ⁠@model⁠ slot, returning the output if available.

Usage

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

Arguments

object	The lcModel object.
...	Additional arguments.

Value

A named ⁠numeric vector⁠ with all coefficients, or a matrix with each column containing the cluster-specific coefficients. If coef() is not defined for the given model, an empty ⁠numeric vector⁠ is returned.

Implementation

Classes extending lcModel can override this method to return model-specific coefficients.

coef.lcModelExt <- function(object, ...) {
  # return model coefficients
}
