Recur-class function

An S4 Class Representing Formula Response for Recurrent Event Data

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. class

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.
