addNDSet2D: Add 2D discrete points to a non-dominated set and classify them into extreme supported, non-extreme supported, non-supported.

Description

Add 2D discrete points to a non-dominated set and classify them into extreme supported, non-extreme supported, non-supported.

Usage

addNDSet2D(pts, nDSet = NULL, crit = "max", keepDom = FALSE)

Value

A data frame with columns z1 and z2, nD (non-dominated), ext (extreme), nonExt (non-extreme supported).

Arguments

pts

A data frame. It is assumed that z1 and z2 are in the two first columns.

nDSet

A data frame with current non-dominated set (NULL is none yet).

crit

Either max or min.

keepDom

Keep dominated points.

addNDSet2D(pts, nDSet, crit = "max")
addNDSet2D(pts, nDSet, crit = "max", keepDom = TRUE)
addNDSet2D(pts, nDSet, crit = "min")
