In reda: Recurrent Event Data Analysis

An S4 Class Representing Formula Response for Recurrent Event Data

Description

The class Recur is an S4 that represents a formula response for recurrent event data model. The function Recur produces objects of this class. See “Slots” for details.

Slots

.Data

A numeric matrix that consists of the following columns:

• time1: the beginning of time segements;

• time2: the end of time segements;

• id: Identificators of subjects;

• event: Event indicators;

• : terminal: Indicators of terminal events.

call

A function call producing the object.

ID

A character vector for unique original identificators of subjects.

ord

An integer vector for increasingly ordering data by id, time2, and - event. Sorting is often done in the model-fitting steps, where the indices stored in this slot can be used directly.

rev_ord

An integer vector for reverting the ordering of the sorted data (by ord) to its original ordering. This slot is provided to easily revert the sorting.

first_idx

An integer vector indicating the first record of each subject in the sorted matrix. It helps in the data checking produce and may be helpful in model-fitting step, such as getting the origin time.

last_idx

An integer vector indicating the last record of each subject in the sorted data. Similar to first_idx, it helps in the data checking produce and may be helpful in the model-fitting step, such as locating the terminal events.

check

A character string indicating how the data checking is performed. It just records the option that users specified on data checking.

time_class

A character vector preserving the class(es) of input times.
