POSetMinimals: Computing the minimal elements of a poset.

Description

Computes the minimal elements of the input poset, i.e. those elements strictly dominating no other elements.

Usage

POSetMinimals(poset)

Value

A vector of character strings (the names of the minimal 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)

mnms <-POSetMinimals(pos)
