R: Perform tiling windows on a tsibble by row

tile_tsibble {tsibble} | R Documentation

## Perform tiling windows on a tsibble by row

### Description

Perform tiling windows on a tsibble by row

### Usage

    tile_tsibble(.x, .size = 1, .id = ".id")

### Arguments

`.x` | A tsibble.
`.size` | A positive integer for window size.
`.id` | A character naming the new column `.id` containing the partition.

### Rolling tsibble

`slide_tsibble()`, `tile_tsibble()`, and `stretch_tsibble()` provide fast and shorthand for rolling over a tsibble by observations. That said, if the supplied tsibble has time gaps, these rolling helpers will ignore those gaps and proceed.

They are useful for preparing the tsibble for time series cross validation. They all return a tsibble including a new column `.id` as part of the key. The output dimension will increase considerably with `slide_tsibble()` and `stretch_tsibble()`, which is likely to run out of memory when the data is large. Alternatively, you could construct cross validation using `pslide()` and `pstretch()` to avoid the memory issue.

### Examples

    harvest <- tsibble(
      year = rep(2010:2012, 2),
      fruit = rep(c("kiwi", "cherry"), each = 3),
      kilo = sample(1:10, size = 6),
      key = fruit, index = year
    )
    harvest %>%
      tile_tsibble(.size = 2)
