count_gaps {tsibble}

Count implicit gaps

Description

Count implicit gaps

Usage

count_gaps(
  .data,
  .full = FALSE,
  .name = c(".from", ".to", ".n"),
  .start = NULL,
  .end = NULL
)

Arguments

.data

A tsibble.

.full

• FALSE inserts NA for each keyed unit within its own period.

• TRUE fills NA over the entire time span of the data (a.k.a. fully balanced panel).

• start() pad NA to the same starting point (i.e. ⁠min(<index>)⁠) across units.

• end() pad NA to the same ending point (i.e. ⁠max(<index>)⁠) across units.

.name

Strings to name new columns.

.start, .end

Set custom starting/ending time that allows to expand the existing time spans.

Value

A tibble contains:

• the "key" of the tbl_ts

• ".from": the starting time point of the gap

• ".to": the ending time point of the gap

• ".n": the number of implicit missing observations during the time period
