tsibble (version 0.3.0)

count_gaps: Count implicit gaps

Description

count_gaps() counts gaps for a tsibble; gaps() find where the gaps in x with respect to y.

Usage

count_gaps(.data, ...)
# S3 method for tbl_ts
count_gaps(.data, ...)
# S3 method for grouped_ts
count_gaps(.data, .full = FALSE, ...)
gaps(x, y)

Arguments

.data

A tbl_ts.

...

Other arguments passed on to individual methods.

.full

FALSE to find gaps for each group within its own period. TRUE to find gaps over the entire time span of the data.

x, y

A vector of numbers, dates, or date-times. The length of y must be greater than the length of x.

Value

A tibble contains:

• the "key" of the tbl_ts

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

• "end": the ending time point of the gap

• "n": the implicit missing observations during the time period
