bootControl: Control object for bootstrap samples

Description

Generate an object that controls how to draw bootstrap samples and which bootstrap estimator of prediction error to compute.

Usage

bootControl(R = 1, type = c("0.632", "out-of-bag"), grouping = NULL)

Arguments

R

an integer giving the number of bootstrap samples.

type

a character string specifying a bootstrap estimator. Possible values are "0.632" (the default), or "out-of-bag".

grouping

a factor specifying groups of observations.

Value

An object of class "bootControl" with the following components:

R

an integer giving the number of bootstrap samples.

type

a character string specifying the type of bootstrap estimator.

grouping

if supplied, a factor specifying groups of observations. The groups will then be resampled rather than individual observations such that all observations within a group belong either to the bootstrap sample or the test data.
