add_resample_id: Augment a data set with resampling identifiers

In tidymodels/rsample: General Resampling Infrastructure

Augment a data set with resampling identifiers

Description

For a data set, add_resample_id() will add at least one new column that identifies which resample that the data came from. In most cases, a single column is added but for some resampling methods, two or more are added.

Usage

add_resample_id(.data, split, dots = FALSE)

Arguments

.data	A data frame.
split	A single rset object.
dots	A single logical: should the id columns be prefixed with a "." to avoid name conflicts with .data?

Value

An updated data frame.

  add_resample_id(car_folds$splits[[1]]) %>%
  head()

car_bt <- bootstraps(mtcars)

analysis(car_bt$splits[[1]]) %>%
  add_resample_id(car_bt$splits[[1]]) %>%
  head()
