## Internal Functions Used in timetk

### Description

The following are internal functions that are not meant to be used by users.

### Usage

    tk_ts_.data.frame(data, select, start, end, frequency, deltat, ts.eps, silent)

    tk_ts_.default(data, select, start, end, frequency, deltat, ts.eps, silent)

    tk_zooreg_.data.frame(
      data,
      select,
      date_var,
      start,
      end,
      frequency,
      deltat,
      ts.eps,
      order.by,
      silent
    )

    tk_zooreg_.default(
      data,
      select,
      date_var,
      start,
      end,
      frequency,
      deltat,
      ts.eps,
      order.by,
      silent
    )

### Arguments

`data` | A time-based tibble or time-series object.
`select` | Applicable to tibbles and data frames only. The column or set of columns to be coerced to `zooreg` class.
`start` | the time of the first observation. Either a single number or a vector of two integers, which specify a natural time unit and a (1-based) number of samples into the time unit.
`end` | the time of the last observation, specified in the same way as `start`.
`frequency` | the number of observations per unit of time.
`deltat` | the fraction of the sampling period between successive observations; e.g., 1/12 for monthly data. Only one of `frequency` or `deltat` should be provided.
`ts.eps` | time series comparison tolerance. Frequencies are considered equal if their absolute difference is less than `ts.eps`.
`silent` | Used to toggle printing of messages and warnings.
`date_var` | Applicable to tibbles and data frames only. Column name to be used to `order.by`. `NULL` by default. If `NULL`, function will find the date or date-time column.
`order.by` | a vector by which the observations in `x` are ordered. If this is specified the arguments `start` and `end` are ignored and `zoo(data, order.by, frequency)` is called. See `zoo` for more information.
