Bootstrap Indices

Description

Generate a series of bootstrap indices.

Usage

bootid(n, R)

Arguments

Details

The function [bootid()] generates the same bootstrap indices as those generated from the default options of function boot (i.e., ‘sim = ’ordinary'' and 'm = 0').

Value

The function [bootid()] returns a length-R list of positive integer vectors. Each element is the length-n indices of each bootstrap sample.

See Also

The function [bootid()] is inspired by functions 'boot:::index.array' and 'boot:::ordinary.array'.

Examples

set.seed(1345); (bt1 = boot::boot(data = 1:10, statistic = function(data, ind) ind, R = 3L)[['t']])
set.seed(1345); (bt2 = do.call(rbind, bootid(10L, R = 3L)))
stopifnot(identical(bt1, bt2))
