boot.samples {InPosition}

Compute indicies for bootstrap resampling.

Description

This function computes a set of indicies for bootstrap resampling. It can be unconstrained or bootstrap within a group design.

Usage

boot.samples(DATA, DESIGN = NULL, constrained = FALSE)

Arguments

DATA

The original data matrix to be bootstrapped. Rows will be bootstrapped and are assumed to be observations.

DESIGN

A design matrix (in disjunctive coding). Only used if constrained is TRUE.

constrained

a boolean. If TRUE, bootstrap resampling will occur within groups as designated by the DESIGN matrix.

Value

a set of indicies to be used to be used as the bootstrap resampled indices.
