splitControl {perry}

Control object for random data splits

Description

Generate an object that controls how to split n observations or groups of observations into training and test data to be used for (repeated) random splitting (also known as random subsampling or Monte Carlo cross-validation).

Usage

splitControl(m, R = 1, grouping = NULL)

Arguments

m

an integer giving the number of observations or groups of observations to be used as test data.

R

an integer giving the number of random data splits.

grouping

a factor specifying groups of observations.

Value

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

m

an integer giving the number of observations or groups of observations to be used as test data.

R

an integer giving the number of random data splits.

grouping

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