R: Update key and index for a tsibble

update_tsibble {tsibble} | R Documentation

## Update key and index for a tsibble

### Description

Update key and index for a tsibble

### Usage

    update_tsibble(x, key, index, regular = is_regular(x), validate = TRUE,
      .drop = key_drop_default(x))

### Arguments

`x` | A tsibble.
`key` | Unquoted variable(s) that uniquely determine time indices. `NULL` for empty key, and works with tidy selector (e.g. `dplyr::starts_with()`).
`index` | A bare (or unquoted) variable to specify the time index variable.
`regular` | Regular time interval (`TRUE`) or irregular (`FALSE`). The interval is determined by the greatest common divisor of index column, if `TRUE`.
`validate` | `TRUE` suggests to verify that each key or each combination of key variables leads to unique time indices (i.e. a valid tsibble). If you are sure that it's a valid input, specify `FALSE` to skip the checks.
`.drop` | If `TRUE`, empty key groups are dropped.

### Details

Unspecified arguments will inherit the attributes from `x`.

### Examples

    library(dplyr)
    pedestrian %>%
      group_by_key() %>%
      mutate(Hour_Since = Date_Time - min(Date_Time)) %>%
      update_tsibble(index = Hour_Since)
