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

Arguments

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.

Value

A list object suitable for use as a subset object
