new_data {tsibble} | R Documentation

## New tsibble data and append new observations to a tsibble

### Description

`append_row()`: add new rows to the end of a tsibble by filling a key-index pair and `NA` for measured variables.

`append_case()` is an alias of `append_row()`.

### Usage

    new_data(.data, n = 1L, ...)

    ## S3 method for class 'tbl_ts'
    new_data(.data, n = 1L, keep_all = FALSE, ...)

    append_row(.data, n = 1L, ...)

### Arguments

`.data` | A `tbl_ts`.
`n` | An integer indicates the number of key-index pair to append.
`...` | Passed to individual S3 method.
`keep_all` | If `TRUE` keep all the measured variables as well as index and key, otherwise only index and key.

### Examples

    new_data(pedestrian)
    new_data(pedestrian, keep_all = TRUE)
    new_data(pedestrian, n = 3)
    tsbl <- tsibble(
      date = rep(as.Date("2017-01-01") + 0:2, each = 2),
      group = rep(letters[1:2], 3),
      value = rnorm(6),
      key = group
    )
    append_row(tsbl)
    append_row(tsbl, n = 2)
