boot.samples: 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)

Value

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

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.
