In strapgod: Resampled Data Frames

Description

When collect() is used on a resampled_df, the virtual bootstrap groups are made explicit.

Usage

## S3 method for class 'resampled_df'
collect(x, ..., id = NULL, original_id = NULL)

Arguments

x	A resampled_df.
...	Not used.
id	Optional. A single character that specifies a name for a column containing a sequence from 1:n for each bootstrap group.
original_id	Optional. A single character that specifies a name for a column containing the original position of the bootstrapped row.

Examples

library(dplyr)

# virtual groups become real rows
collect(bootstrapify(iris, 5))

# add on the id column for an identifier per bootstrap
collect(bootstrapify(iris, 5), id = ".id")

# add on the original_id column to know which row this bootstrapped row
# originally came from
collect(bootstrapify(iris, 5), original_id = ".original_id")
