levels.incidence and levels.cover: Levels of a poset

Description

The behaviour of these methods for objects of classes incidence and cover is different from the behaviour of function levels for factors. Because of the technical definition it is not possible to use a different name for these methods. The methods return a vector associating each profile with the corresponding level.

Usage

## S3 method for class 'incidence':
levels(x)
## S3 method for class 'cover':
levels(x)

Arguments

x

an object of class cover or incidence.

Examples

vl <- c(3, 2, 4)
prof <- var2prof(varlen = vl)
Z <- getzeta(prof)

levels(Z)
