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)
.data |

split |
A single |
dots |
A single logical: should the id columns be prefixed with a "."
to avoid name conflicts with |
An updated data frame.
