subset_maker: Create a simple subset object

Description

Given an integer vector whose \(i^\mathrm{th}\) element is the number of runs at level \(i\), return a subset object in echelon form.

Usage

subset_maker(x)

Value

A list object suitable for use as a subset object

Arguments

x

A vector of integers

Author

Robin K. S. Hankin

Details

In this context, x being in “echelon form” means that

  • x is consistent in the sense of passing is.consistent()

  • For each \(i\), x[[i]] = 1:n for some \(n\).

See Also

is.consistent, is.nested, is.strict

Examples

Run this code
subset_maker(c(10,4,3))


is.nested(subset_maker(c(4,9,6))) #should be FALSE
is.nested(subset_maker(c(9,6,4))) #should be TRUE
