Description

Base class used to define a longitudinal cluster method. It is implemented as a wrapper around a call.

Model estimation is handled through a series of calls implement by the lcMethod object. The calls are made by latrend, in the following order:

• compose

• validate

• prepareData

• preFit

• fit

• postFit

Extracts the assigned label.

Extracts the name of the given object.

Usage

Arguments

Details

Because the lcMethod arguments may be unevaluated, evaluation functions such as [[ accept an envir argument. A default environment can be assigned or obtained from a lcMethod object using the environment() function.

Value

The updated lcMethod object.

An lcModel object.

The extracted label, as character.

A character vector of argument names.

An environment that will be passed to fit().

A data.frame with the post-processed data.

The updated lcModel object.

Either TRUE if all validation checks passed, or a character containing a description of the failed validation checks.

Slots

arguments

A list representing the arguments of the lcMethod object. Arguments are not evaluated upon creation of the method object. Instead, arguments are stored similar to a call object. Do not modify or access.

sourceCalls

A list of calls for tracking the original call after substitution. Used for printing objects which require too many characters (e.g. ,function definitions, matrices).
