add_resample_id function

Augment a data set with resampling identifiers

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.

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?

Returns

An updated data frame.

Examples

library(dplyr)

set.seed(363)
car_folds <- vfold_cv(mtcars, repeats = 3)

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

car_bt <- bootstraps(mtcars)

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