POSetMaximals: Computing the maximal elements of a poset.

Description

Computes the maximal elements of the input poset, i.e. those elements being strictly dominated by no other elements.

Usage

POSetMaximals(poset)

Value

A vector of character strings (the names of the maximal elements).

Arguments

poset

An object of S4 class POSet. Argument poset must be created by using any function contained in the package aimed at building object of S4 class POSet (e.g. POSet(), LinearPOSet(), ProductPOSet(), ...) .

Examples

elems <- c("a", "b", "c", "d")

dom <- matrix(c(
  "a", "b"
  ,
  "c", "b",
  "b", "d"
), ncol = 2, byrow = TRUE)

pos <- POSet(elements = elems, dom = dom)

mxs <- POSetMaximals(pos)
