Time vector classes

Source: R/00_classes.R
mt_time-class.Rd

The mt_time family are the S7 vector classes that store time points as a numeric count of chronons. mt_time is the (internal) base class carrying the chronon property; the common modes of time are:

  • mt_linear - linear time points, typically produced with linear_time().

  • mt_cyclical - cyclical time points with additional cycle granule, typically produced with cyclical_time().

  • mt_duration - time durations, typically produced with duration().

The underlying data can be either integer (discrete time) or double (continuous time). The chronon (and, for mt_cyclical, the cycle) are time granules, the result from a mt_unit object.

Usage

mt_linear(.data = integer(), chronon = mt_unit(1L))

mt_duration(.data = integer(), chronon = mt_unit(1L))

mt_cyclical(.data = integer(), chronon = mt_unit(1L), cycle = mt_unit(1L))

Arguments

.data

A numeric vector of chronon counts (integer or double).

chronon, cycle

Time granules (mt_unit objects) giving the unit of the chronon counts and, for mt_cyclical, the length of the cycle.

Value

An S7 class object (used for method dispatch), or a time vector when called as a constructor.
